    • To improve health care for older persons, we need to learn more about ageing, e.g. identify protective factors and early markers for diseases. The Gothenburg H70 Birth Cohort Studies (the H70 studies) are multidisciplinary epidemiological studies examining representative birth cohorts of older populations in Gothenburg, Sweden. So far, six birth cohorts of 70-year-olds have been examined over time, and examinations have been virtually identical between studies. This paper describes the study procedures for the baseline examination of the Birth cohort 1944, conducted in 2014-16. In this study, all men and women born 1944 on specific dates, and registered as residents in Gothenburg, were eligible for participation (n=1839). A total of 1203 (response rate 72.2%; 559 men and 644 women; mean age 70.5years) agreed to participate in the study. The study comprised sampling of blood and cerebrospinal fluid, psychiatric, cognitive, and physical health examinations, examinations of genetics and family history, use of medications, social factors, functional ability and disability, physical fitness and activity, body composition, lung function, audiological and ophthalmological examinations, diet, brain imaging, as well as a close informant interview, and qualitative studies. As in previous examinations, data collection serves as a basis for future longitudinal follow-up examinations. The research gained from the H70 studies has clinical relevance in relation to prevention, early diagnosis, clinical course, experience of illness, understanding pathogenesis and prognosis. Results will increase our understanding of ageing and inform service development, which may lead to enhanced quality of care for older persons.

  • Changes in lifestyle among prostate cancer survivors: A nationwide population-based study
  • 2020
  • Ingår i: Psycho-Oncology. - : Wiley. - 1057-9249 .- 1099-1611. ; 29:10
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective Long-term information on lifestyle changes among prostate survivors is lacking. In this nationwide, population-based study we investigated the prevalence of lifestyle changes, factors associated with lifestyle changes and associations between lifestyle changes and general quality of life. Methods All men registered in the National Prostate Cancer Register of Sweden diagnosed in 2008 with low-risk prostate cancer at age 70 years or younger were sent a questionnaire. Logistic regression was used to calculate odds ratios (ORs) with 95% confidence intervals for factors potentially associated with lifestyle change. Results Out of 1288, 1720 men (75%) were responded. A total of 279 (22%) reported a positive lifestyle change regarding diet or exercise. Poor functional outcomes after treatment was associated with exercising less (OR 1.6, 95% CI 1.2-2.1) and less interest in social activities and relationships (OR 1.8, 95% CI 1.5-2.1). Men who exercised more (OR 7.9, 95% CI 4.4-14) and men who had an increased interest in relationships and social activities (OR 5.2, 95% CI 2.1-13) reported higher general quality of life. Conclusions A considerable proportion of men reported making positive lifestyle changes after the prostate cancer diagnosis. The time after diagnosis may be a teachable moment that facilitates lifestyle interventions. Poor functional outcomes after treatment may reduce the willingness to engage in positive lifestyle change, which need be considered when supporting men after treatment. Men who made a positive lifestyle change, regardless of whether it was exercise or regarding relationships and social activities more often reported a high level of general quality of life.

  • PSA testing patterns in a large Swedish cohort before the implementation of organized PSA testing
  • 2020
  • Ingår i: Scandinavian journal of urology. - : Taylor & Francis. - 2168-1805 .- 2168-1813. ; 54:5, s. 376-381
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Organized PSA testing for asymptomatic men aged 50-74 years will be implemented in Sweden to reduce opportunistic testing in groups who will not benefit. The aim of this study was to describe the opportunistic PSA testing patterns in a Swedish region before the implementation of organized PSA testing programs.Method: We included all men in the Uppsala-orebro health care region of Sweden who were PSA tested between 1 July 2012 and 30 June 2014. Information regarding previous PSA testing, prostate cancer diagnosis, socioeconomic situation, surgical procedures and prescribed medications were collected from population-wide registries to create the Uppsala-orebro PSA cohort (UPSAC). The cohort was divided into repeat and single PSA testers. The background population used for comparison consisted of men 40 years or older, living in the Uppsala-orebro region during this time period.Results: Of the adult male population in the region, 18.1% had undergone PSA testing. Among men over 85 years old 21% where PSA tested. In our cohort, 62.1% were repeat PSA testers. Of men with a PSA level <= 1 mu g/l 53.8% had undergone repeat testing. Prostate cancer was found in 2.7% and 4.8% of the repeat and single testers, respectively.Conclusion: Every fifth man in the male background population was PSA tested. Repeated PSA testing was common despite low PSA values. As repeated PSA testing was common, especially among older men who will not be included in organized testing, special measures to change the testing patterns in this group may be required.

  • Landscape of surfaceome and endocytome in human glioma is divergent and depends on cellular spatial organization
  • 2022
  • Ingår i: Proceedings of the National Academy of Sciences of the United States of America. - : Proceedings of the National Academy of Sciences (PNAS). - 0027-8424 .- 1091-6490. ; 119:9

    • Therapeutic strategies directed at the tumor surfaceome (TS), including checkpoint inhibitor blocking antibodies, antibody drug conjugates (ADCs), and chimeric antigen receptor T (CAR-T) cells, provide a new armament to fight cancer. However, a remaining bottleneck is the lack of strategies to comprehensively interrogate patient tumors for potential TS targets. Here, we have developed a platform (tumor surfaceome mapping [TS-MAP]) integrated with a newly curated TS classifier (SURFME) that allows profiling of primary 3D cultures and intact patient glioma tumors with preserved tissue architecture. Moreover, TS-MAP specifically identifies proteins capable of endocytosis as tractable targets for ADCs and other modalities requiring toxic payload internalization. In high-grade gliomas that remain among the most aggressive forms of cancer, we show that cellular spatial organization (2D vs. 3D) fundamentally transforms the surfaceome and endocytome (e.g., integrins, proteoglycans, semaphorins, and cancer stem cell markers) with general implications for target screening approaches, as exemplified by an ADC targeting EGFR. The TS-MAP platform was further applied to profile the surfaceome and endocytome landscape in a cohort of freshly resected gliomas. We found a highly diverse TS repertoire between patient tumors, not directly associated with grade and histology, which highlights the need for individualized approaches. Our data provide additional layers of understanding fundamental to the future development of immunotherapy strategies, as well as procedures for proteomics-based target identification and selection. The TS-MAP platform should be widely applicable in efforts aiming at a better understanding of how to harness the TS for personalized immunotherapy.

  • Inflammatory response to oxidised surface with Mg 2+ -ions incorporated in vitro
  • 2004
  • Ingår i: 7th World Biomaterials Congress, Sidney, 17 -21 May 2004.
  • Konferensbidrag (refereegranskat)abstract
    • Introduction Oxide films that grow spontaneously on titanium surfaces in contact with air may explain the bio-passivity of the material. Various procedures have been carried out to modify the properties of titanium oxide films to further improve the biocompatibility. Anodic oxidation is one technique to increase the thickness of the oxide layer that demonstrates significant stronger bone response in vivo. The concomitant increase in surface roughness and size and presence of pores of the thicker oxide layer seems to work as a potential contributor to the results (1). Attempts to implant ion in the oxide layers to overcome the drawbacks of calcium phosphate coatings (hydroxylapatite) such as i.e. delaminating and biodegradation during function seem promising (2). However the reasons why a thicker oxide layer with and without incorporated ions is favourable compared to conventionally turned and blasted surfaces are not fully understood. The aim of this study was to compare the early inflammatory response to the turned, blasted and electrochemically oxidised surface with Mg 2+ ions incorporated. Materials and Methods A total of 108 pure titanium discs were prepared with a turned surface. Thirty-six were kept as turned controls while 36 were blasted with 75 μm Al2O3 particles and 36 underwent electrochemically oxidation and Mg 2+ ion incorporation. MicroXam™, (Phase-Shift, Tucson, Arizona, USA) was used to for topographical characterisation. The disks were incubated with human mononuclear cells isolated from buffy coats of healthy blood donors (C-lab, Blood Supply Unit Sahlgrenska University hospital, Sweden) and cultured at a concentration of 106 cells/ml in 24 well cell culture plates. Half of the discs with the different treated surfaces were immediately treated with LPS while half were left without any stimuli. The incubation times were 24 and 72h. After each incubation period the incubation medium was collected and centrifuged. The supernatant was analysed with respect to cell viability and cytokine levels. Cell viability was estimated by analysing the content of lactatdehydrogenas (LDH)(Sahlgrenska University hospital, C-lab) and a commercially available ELISA assay (Biotrak system™, Amersham Bioscience, UK) was used to quantify TNF-α and IL -10 levels. The cells adherent to the material was stained with 2,6- diamidino-2-phenyindole (DAPI) (Sigma, USA) to evaluate the total cell number. In order to characterize differentiation of the adherent cells expression of 27E10 and RM3/1 (Biogenisis, UK) was used. The marker 27E10 and RM3/1 define acute and chronic inflammatory phenotypes respectively. Differentiated cells were evaluated as the percentage of positively stained cells from the total cell numbers. Results Surface evaluation revealed similar roughness for the turned control and the anodised surface with Mg 2+ ions incorporated while the blasted surface demonstrated a rougher surface profile (fig 1, 2). Fig 1 Fig 2 Sa-average height deviation (ym) SURFACE CTR Blasted Anodised+Mg Mean SA 1,2 1,0 ,8 ,6 ,4 ,2 0,0 Sdr-developed surface area (%) SURFACE CTR Blasted Anodised+Mg Mean SDR 40 30 20 10 0 LDH values were generally low for all surfaces (within the range of 0.8-1.6 μkat/l) but were slightly increased after LPS stimulation and after 72h. TNF-α was transient higher day one and after LPS stimulation especially on the turned control surface (fig 3, 4) Fig 3 Fig 4 TNF-a 24h (pg/ml) SURFACE CTR Blasted Anodised+Mg Mean C 3000 2000 1000 0 LPS LPSLPS+ TNF-a 72h (pg/ml) SURFACE CTR Blasted Anodised+Mg Mean C 400 300 200 100 0 LPS LPSLPS+ IL-10 levels were generally low irrespective of time. Increased IL-10 amounts after LPS stimulation and after 24 h were observed for all surfaces. The total cell numbers decreased on all surfaces from 24h to 72h but there were no major difference between stimulated and un-stimulated wells. Acute monocytic phenotype 27E10 marker dominated on all surfaces while the expression of the chronic RM3/1 marker was almost absent on all surfaces both at 24 and 72h. Conclusion The present study indicates a surface topography- and chemistry related difference in the acute inflammatory response with a stronger acute inflammatory response to the turned control compared to the blasted and anodised surface with Mg 2+ ions incorporated.

  • Inflammatory response to titanium surfaces with with Potential Bioactive Properties: An In Vitro Study
  • 2006
  • Ingår i: Clinical Implant Dentistry and Related Research. ; 8:4, s. 210-217
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The current hard tissue implants research aims to accelerate bone healing by designing surfaces that are bioactive. However, the role of the inflammatory response to these surfaces is so far incompletely described. Purpose: The aim of the study was to evaluate early inflammatory response in vitro to a potentially bioactive surface—an anodized surface with Mg ions incorporated (anodized/Mg)—and to compare it to a turned, a blasted, and an anodized surface. Materials and Methods: An interferometer was used for topographical characterizations. The disks were incubated with human mononuclear cells. Adherent cells were investigated with respect to number of cells, viability, differentiation, and cytokine production with and without lipopolysaccharide stimulation after 24 and 72 hours. Results: The number of adhered mononuclear cells differed significantly between the different modified surfaces, with the highest number on the anodized surface. However, there were no significant differences in cytokine production and differentiation between the different modified surfaces. The amount of anti-inflammatory mediator interleukin-10 remained over time, while the number of cells and pro-inflammatory cytokine tumor necrosis factor-α decreased. The cells were viable on all surfaces, respectively. Conclusion: The anodized surfaces with and without Mg ions showed an increased cell adherence, however, otherwise an inflammatory response similar to the turned and blasted surfaces. Furthermore, the potentially bioactive anodized/Mg surface showed a similar response to the TiUnite-like anodized surface despite the former having a surface roughness of a smoother character.

    • The innate immune system and in particular the pattern-recognition receptors Toll-like receptors have recently been linked to atherosclerosis. Consequently, inhibition of various signaling molecules downstream of the Toll-like receptors has been tested as a strategy to prevent progression of atherosclerosis. Receptor-interacting protein 2 (Rip2) is a serine/threonine kinase that is involved in multiple nuclear factor-κB (NFκB) activation pathways, including Toll-like receptors, and is therefore an interesting potential target for pharmaceutical intervention.

  • Simplified Postoperative Care After Spring-assisted Strip Craniotomy for Sagittal Synostosis: A Prospective Before-and-After Study.
  • 2021
  • Ingår i: The Journal of craniofacial surgery. - 1536-3732. ; 32:4, s. 1507-1510
  • Tidskriftsartikel (refereegranskat)abstract
    • Since the development of spring-assisted techniques for corrective craniofacial surgery, routine postoperative admission to intensive care units (ICUs) has been questioned. However, close monitoring is necessary if the continuous infusion of morphine is used as recommended for better pain relief. In this study, the authors evaluated a simplified postoperative protocol without continuous morphine infusion and no indwelling urinary catheter following spring-assisted surgery (SAS) for sagittal synostosis. Ten children were cared for according to a standard protocol with postoperative intravenous (i.v.) infusion of morphine and an indwelling urinary catheter, and 11 consecutive children were treated according to a simplified protocol with pain relief based on intermittent injections of morphine and clonidine [according to Face, Legs, Activity, Cry, Consolability (FLACC) scores >4] without the indwelling catheter. A Mann-Whitney U test was used for comparison of distributions between the two groups. The results revealed no differences between groups regarding the proportion of FLACC scores >4, total amount of administered i.v. morphine and clonidine, total volume of buffered glucose infused, time to first feeding on breast milk or substitute, or the length of stay. Despite the inherent limitations of our small observational study, the authors concluded that at our institution, it was possible to exclude a standard continuous i.v. infusion of morphine and an indwelling urinary catheter from our postoperative care protocol without decreasing the quality of pain relief in children submitted to SAS for sagittal synostosis. This finding supports downgrading the level of care from the ICU to a regular ward after limited immediate postoperative observation.

  • Impacts on fuel producers and customers of conflicting rules for life cycle assessment
  • 2022
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • The use of life cycle assessment (LCA) as a tool for estimating the environmental performance of a product or service in a holistic and systematic manner is increasing. Fuel producers may need to apply different methodological frameworks to be used in different contexts; internally for product development activities as well as externally for communication with customers or authorities. Different LCA frameworks may vary in scope, system boundaries (i.e. life cycle stages to be considered) or modelling requirements (such as data demands but also more detailed methodological features). They may also vary in terms of information they can provide in relation to the environmental performance of the product. Those variations could lead to conflicting outcomes and conclusions and may also increase complexity for the LCA practitioner leading to high competence and resource requirements. Within the research project: Impacts on fuel producers and customers of conflicting rules for LCA , the requirements of different LCA frameworks and their implications to fuel producers are investigated. Focus has been given on three specific frameworks that are identified as relevant or potentially relevant for fuel producers, namely: the recast of the EU Renewable Energy Directive (referred to here as RED II), the EU framework for Product Environmental Footprint (PEF), and the framework of Environmental Product Declaration (EPD). The aim of the project is to increase understanding on the different LCA frameworks available and identify whether the multitude of such frameworks gives conflicting recommendations for environmental improvements and fuel choices.   The three LCA frameworks listed above were applied in case studies. To illustrate the potential differences that the different frameworks may lead to, a variation of production pathways and feedstocks were selected including first generation as well as advanced biofuels. Based on the results obtained it can be concluded that applying all three frameworks is not a straightforward task. The methods contain fundamental differences and are at different levels of development, maturity, and adoption. In certain situations, they can lead to diverging conclusions as a result of different quantitative outcomes for a specific production pathway, thus influencing decision making processes in different directions. Understanding those differences and underlying assumptions is important for understanding the variations in outcome. The result for a specific fuel could differ substantially depending on the framework applied and the assumptions and interpretations made when applying this framework. Certain methodological parameters were identified to have a greater impact on the results than others: • The three frameworks diverge in the methods applied for modelling waste management, which can be very important for the results when the biofuel is produced from waste. • The frameworks diverge in what approaches are allowed for modelling processes with multiple products. This can be very important for the results when the fuel is co-produced with other products. • The frameworks also diverge in how the electricity supply is modelled. This is not very important for the results in most of our case studies, because the production of these biofuels does not require a lot of electricity. The study confirms that applying a framework like EPD or PEF in addition to RED II would require significant supplementary efforts. Not only because of different rules which were often contradicting or difficult to interpret but also because of additional data and reporting requirements. The need for expertise and resources is increasing for fuel producers to be able to provide EPD and PEF compliant assessments. To enhance the development and harmonization of LCA approaches this project stresses the need for product specific rules (in the form of Product Environmental Category Rules (PEFCR) and Product Category Rules (PCR)) for renewable fuels. Future versions of all three studied frameworks should be clearer on how specific methodological choices are to be applied (e.g., when it comes to allocation and multifunctional processes) as well as when it comes to model electricity supply. RED for example shall be clearer on how to define the electricity region while EPD guidelines on how to define the electricity market. Although it is not realistic to aim for a single unified LCA framework, the biofuel PCR and PEFCR can be developed with RED in mind. Some aspects of the PEF methodology can perhaps also be integrated into RED III that is currently under development. This would enhance the broader adoption of the frameworks among fuel producers. Finally, the involvement and engagement of the industry, and fuel producers themselves is very important. Industry initiatives are essential for the development of biofuel PCR and PEFCR while the general development of the three frameworks can also be influenced. In this study, we also investigated the relationship between the LCA frameworks and schemes for chain of custody certification (CoCC), in particular schemes for mass balance certifications (MBC) to investigate to what extent these schemes complement or overlap with LCA. The purpose of MBC schemes and LCA are different, in the sense that the first aim at verifying the sources and sustainability of total amounts of raw materials used by tracking them throughout the value chain, while the second at quantifying specific environmental impact. The system boundaries are similar, since both cover the entire value chain, but may be applied differently depending on the detailed frameworks applied and choices made in applying the MBC schemes. By identifying and clearly illustrating the variations among the studied frameworks the study enhances application, development, and harmonization of LCA, in a broader perspective, informs LCA practitioners but also decision makers and provides insights on how the identified challenges can be addressed.

  • Psychosocial Self-efficacy and its Association with Selected Potential Factors Among Adults with Type 1 Diabetes : A Cross-Sectional Survey Study
  • 2024
  • Ingår i: Diabetes Therapy. - : Springer. - 1869-6953 .- 1869-6961. ; 15:6, s. 1361-1373

    • Introduction The management of type 1 diabetes, a non-preventable chronic disease, leads to a high physical and psychological burden on the individual. Digital health technology can improve a person's psychosocial self-efficacy and thereby contribute to improved diabetes self-care. The aim of this study was to explore associations between psychosocial self-efficacy and demographic-, disease specific-, well-being as well as digital health technology (DHT) related factors among adults with type 1 diabetes.Methods A primarily web-based cross sectional survey was conducted among adults with type 1 diabetes in Sweden (n = 301). Psychosocial self-efficacy was assessed using the Swedish version of the Diabetes Empowerment Scale, Swe-DES-23. The survey also contained questions related to demographic-, disease specific-, well-being as well as digital health technology related variables.Results Higher well-being scores and lower HbA1c levels were associated with higher psychosocial self-efficacy in multiple linear regression analysis. In multivariate analysis, gender, body mass index, well-being scores, and HbA1c levels showed association with psychosocial self-efficacy. None of the DHT factors were found associated with psychosocial self-efficacy.Conclusions In this study, higher well-being score and lower self-reported HbA1c levels were associated with higher psychosocial self-efficacy in both univariate- and multivariate analysis and accounted for 30% of the variation in psychosocial self-efficacy in the regression model. Thus, measures to improve psychosocial self-efficacy in adults with type 1 diabetes may help maintain their psychological well-being and blood glucose control.

    • The colonic mucus layer plays a critical role in intestinal homeostasis by limiting contact between luminal bacteria and the mucosal immune system. A defective mucus barrier in animal models allows bacterial contact with the intestinal epithelium and results in spontaneous colitis. A defective mucus barrier is also a key feature of active ulcerative colitis (UC). Alterations in the immune compartment due to intestinal bacterial breach in mice lacking the colon mucus barrier have not been characterized and correlated to active UC.

    • Objective. The incidence of prostate cancer is rising rapidly in Sweden and there is a need to better understand the pattern of diagnosis, tumor characteristics and treatment. Material and methods. Between 1996 and 2005, all new cases of adenocarcinoma of the prostate gland were intended to be registered in the National Prostate Cancer Register (NPCR). This register contains information on diagnosing unit, date of diagnosis, cause of diagnosis, tumor grade, tumor stage according to the TNM classification in force, serum prostate-specific antigen (PSA) levels at diagnosis and primary treatment given within the first 6 months after diagnosis. Results. In total, 72 028 patients were registered, comprising >97% of all pertinent incident cases of prostate cancer in the Swedish Cancer Register (SCR). During the study period there was a considerable decrease in median age at the time of diagnosis, a stage migration towards smaller tumors, a decrease in median serum PSA values at diagnosis, a decrease in the age-standardized incidence rate of men diagnosed with distant metastases or with a PSA level of >100 ng/ml at diagnosis and an increase in the proportion of tumors with Gleason score ≤6. Relatively large geographical differences in the median age at diagnosis and the age-standardized incidence of cases with category T1c tumors were observed. Treatment with curative intent increased dramatically and treatment patterns varied according to geographical region. In men with localized tumors and a PSA level of <20 ng/ml at diagnosis, expectant treatment was more commonly used in those aged ≥75 years than in those aged <75 years. Also, the pattern of endocrine treatment varied in different parts of Sweden. Conclusions. All changes in the register seen over time are consistent with increased diagnostic activity, especially PSA testing, resulting in an increased number of cases with early disease, predominantly tumors in category T1c. The patterns of diagnosis and treatment of prostate cancer vary considerably in different parts of Sweden. The NPCR continues to be an important source for research, epidemiological surveillance of the incidence, diagnosis and treatment of prostate cancer

  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction Overtreatment of localised prostate cancer is substantial despite increased use of active surveillance. No randomised trials help define how to monitor patients or when to initiate treatment with curative intent. Methods and analysis A randomised, multicentre, intervention trial designed to evaluate the safety of an MRI-based active surveillance protocol, with standardised triggers for repeated biopsies and radical treatment. The aim is to reduce overtreatment of prostate cancer. 2000 men will be randomly allocated to either surveillance according to current practice or to standardised triggers at centres in Sweden, Norway, Finland and the UK. Men diagnosed in the past 12 months with prostate cancer, ≤T2a, prostate-specific antigen (PSA) <15 ng/mL, PSA density ≤0.2 ng/mL/cc, any International Society of Urological Pathology (ISUP) grade 1 are eligible. Men with ISUP grade 2 in <30% of cores on systematic biopsy and <10 mm cancer in one core on systematic or targeted biopsy are also eligible. Men diagnosed on systematic biopsy should have an MRI and targeted biopsies against Prostate Imaging and Reporting Data System V.2 3-5 lesions before inclusion. Identical follow-up in the two study arms: biannual PSA testing, yearly clinical examination and MRI every second year. In the experimental arm, standardised triggers based on MRI and PSA density elicit repeated biopsies. MRI and histopathological progression trigger radical treatment. Primary outcome measure is progression-free survival. Secondary outcome measures are cumulative incidence of metastatic disease, treatments with curative intent, pT3-4 at radical prostatectomy, switch to watchful waiting, prostate cancer mortality and quality of life. Inclusion started in October 2016 and in October 2018; 275 patients have been enrolled. Ethics and dissemination Ethical approval was obtained in each participating country. Results for the primary and secondary outcome measures will be submitted for publication in peer-reviewed journals. Trial registration number NCT02914873.

    • The focus of this book is on the many far from predictable transformative political processes on gender, sexuality and coloniality that grow out of the broad range of bodies and actors engaged in politics outside the hegemonic order and in everyday activities. These processes are not conducted by states, governments or transnational nongovernmental organisations; rather, they are examples of politics in-between states, organisations and national imagined communities. In this first chapter we will introduce some of the main themes, regarding these processes we in our joint research programme have worked on over the last couple of years.

    • Fibroblasts are central in wound healing by expressing important mediators and producing and remodelling extracellular matrix (ECM) components. This study aimed at elucidating possible mechanisms of action of the ECM protein amelogenin on normal human dermal fibroblasts (NHDF). Amelogenin at 100 and 1000 μg/ml increased binding of NHDF via several integrins, including αvβ3, αvβ5 and α5β1. Further, both surface interaction and cellular uptake of amelogenin by NHDF was observed using scanning and transmission electron microscopy. Gene microarray studies showed >8-fold up or down-regulation of genes, of which most are involved in cellular growth, migration and differentiation. The effect of amelogenin was exemplified by increased proliferation over 7 days. In conclusion, the beneficial effects of amelogenin on wound healing are possibly conducted by stimulating fibroblast signalling, proliferation and migration via integrin interactions. It is hypothesized that amelogenin stimulates wound healing by providing connective tissue cells with a temporary extracellular matrix.

    • Introduction: Inflammation is an integral part of the normal wound healing response. Besides clearing the wound of invading microbes and debris, inflammatory cells are believed to be crucial coordinators of the repair process, acting both as phagocytes and as a major source of growth factors and other signals [1]. In non-healing skin ulcers the repair process is stuck in the inflammation phase [2]. Excessive inflammation can reflect an imbalance in the transformation of phenotype between the classically activated, inflammatory macrophage and the alternatively activated macrophage involved in immunosuppression and tissue repair [3]. Amelogenin is a hydrophobic extracellular matrix protein that under physiological conditions will self assemble into nanospheres which in turn may form larger aggregates. Treatment with amelogenin has shown enhanced skin wound healing in an in vivo study in rabbits [4]. In addition, amelogenin has been proposed to have anti-inflammatory properties by attenuation of lipopolysaccharide (LPS)- and peptidoglucan-induced production of selected pro-inflammatory cytokines by human blood cells [5]. The present study was initiated to determine the effects of amelogenin on human monocyte secretion of factors which modulate both inflammation and tissue repair. Materials and Methods: Lyophilized amelogenin from Biora AB (Malmö, Sweden) was dissolved in 17 mM acetic acid. Human monocytes were obtained from six healthy blood donors by isolation using the separation gradient PercollTM in two steps according to Pertoft et al. [6]. The isolated monocytes were cultured for 24 h at 37ºC with 5% CO2 and 95% humidity. Thereafter the supernatants and non-adherent cells were removed. Fresh medium (RPMI, 5% foetal bovine serum, antibiotics) containing amelogenin, 0, 0.01, 0.1 and 1.0 mg/ml, and with or without addition of LPS, was added to the wells in triplicates. The plates were again incubated for 24 h. The supernatants were analyzed with commercial human ELISA assays for tumour necrosis factor- (TNF-), interleukin-10 (IL-10), macrophage inflammatory protein-1 (MIP-1), monocyte chemoattractant protein-1 (MCP-1), vascular endothelial growth factor (VEGF), and insulin like growth factor-1 (IGF-1). Results: Amelogenin treatment markedly altered the expression of factors by human monocytes. Amelogenin significantly reduced LPS-induced TNF- secretion, whereas the IL-10 expression was increased. Monocyte secretion of the two inflammatory chemokines MIP-1 and MCP-1 (Figure; mean ± SEM, n=6) was also affected by amelogenin treatment. Furthermore, amelogenin significantly increased monocyte secretion of VEGF (Figure; mean ± SEM, n=6) and IGF-1, although to a lesser extent, after 24 h culture. Conclusions: The amelogenin effects correlate to protein concentration, however not in a dose dependent manner, but instead the cell responses may reflect a concentration related difference in self assembly of the amelogenin protein. The observed changes in cytokine and chemokine expression are markedly affected by simultaneous LPS-induced inflammation activation, revealing possible anti-inflammatory properties of the amelogenin protein. In addition, the several-fold increase in VEGF-levels by monocytes provides a possible mechanism for the observed pro-angiogenic effect in vivo [4]. These in vitro results indicate that the extracellular matrix protein amelogenin by virtue of its interaction with human monocytes may modulate inflammation and tissue repair.

    • Purpose: The aim is to explore how family relations are affected by societalchanges in relation to informal and formal caregiving and self-determinationof older adults.Design/methodology/approach: Care managers (CMs)/social workers (SWs)(N = 124) participated in a comparative vignette study including Japan, SouthKorea, and Sweden. Systems theory was used.Findings: Japanese CMs/SWs clearly describe their efforts to create networksin a relational way between formal and informal actors in the community. SouthKorean CMs/SWs balance between suggesting interventions to support dailylife at home or a move to a nursing home, often acknowledging the family as themain caregiver. In Sweden, CMs/SWs highlight the juridical element in meetingthe older adult and the interventions offered, and families primarily give socialsupport. Regarding self-determination, the Japanese priority is for CMs/SWsto harmonize within the family and the community. South Korean CMs/SWsexpress ambivalent attitudes to older adults’ capability for self-determination inthe intersection between formal and family care. Swedish CMs/SWs adhere tothe older adult’s self-determination, while acknowledging the role of the familyin persuading the older adult to accept interventions. The results suggest emergingdefamilialization in South Korea, while tendencies to refamilialization arenoticed in Japan and Sweden, albeit in different ways.Research limitations/implications: In translation, nuances may be lost. Afocus on changing families shows that country-specific details in care serviceshave been reduced. For future research, perspectives of “care” need to be studiedon different levels.Originality/value: Using one vignette in three countries with different welfareregimes, discussing changing views on families’, communities’ and societal caregivingis unique. This captures changes in policy, influencing re- and defamilialization.

    • Acromegaly [overproduction of GH (growth hormone)] is associated with cardiovascular disease. Transgenic mice overexpressing bGH (bovine GH) develop hypertension and hypercholesterolaemia and could be a model for cardiovascular disease in acromegaly. The aims of the present study were to investigate the effects of excess GH on vascular function and to test whether oxidative stress affects endothelial function in bGH transgenic mice. We studied the ACh (acetylcholine)-induced relaxation response in aortic and carotid rings of young (9-11 weeks) and aged (22-24 weeks) female bGH transgenic mice and littermate control mice, without and with the addition of a free radical scavenger {MnTBAP [Mn(III)tetrakis(4-benzoic acid)porphyrin chloride]}. We also measured mRNA levels of eNOS (endothelial nitric oxide synthase) and EC-SOD (extracellular superoxide dismutase). Intracellular superoxide anion production in the vascular wall was estimated using a dihydroethidium probe. Carotid arteries from bGH transgenic mice had an impaired ACh-induced relaxation response (young, 46 +/- 7% compared with 69 +/- 8%; aged, 52 +/- 5% compared with 80 +/- 3%; P < 0.05), whereas endothelial function in aorta was intact in young but impaired in aged bGH transgenic mice. Endothelial dysfunction was corrected by addition of MnTBAP in carotid arteries from young mice and in aortas from aged mice; however, MnTBAP did not correct endothelial dysfunction in carotid arteries from aged bGH transgenic mice. There was no difference in intracellular superoxide anion production between bGH transgenic mice and control mice, whereas mRNA expression of EC-SOD and eNOS was increased in aortas from young bGH transgenic mice compared with control mice (P < 0.05). We interpret these data to suggest that bGH overexpression is associated with a time- and vessel-specific deterioration in endothelial function, initially caused by increased oxidative stress and later by other alterations in vascular function.

  • Effect of molecular mobility of polymeric implants on soft tissue reactions: An in vivo study in rats
  • 2008
  • Ingår i: Journal of Biomedical Materials Research Part A. - : Wiley. - 1552-4965 .- 1549-3296. ; 84A:3, s. 652-660

    • Although numerous different polymers are used as implants or otherwise studied for many other biotechnical applications, there is a lack of basic models that correlate polymer characteristics with foreign body reactions. This study aims at developing one such model by systematically studying surface molecular mobility of polymeric implants in soft tissues in vivo. Changing the length of the alkyl side chain of poly(alkyl methacrylates) (PAMAs), provides an interesting opportunity to study the surface molecular mobility with minimal changes of the hydrophobicity of the surface. Thus, in this study three different PAMAs, with increasingly surface mobility; poly (isobutyl methacrylate) (PIBMA), poly(butyl methacrylate) (PBMA), and poly(lauryl methacralate) (PLMA) along with pure titanium (Ti) substrates were implanted in the dorsum of Sprague-Dawley rats. Inflammatory cell recruitment, cell adhesion, and cytokine release were studied after 1, 3, and 28 days of implantation. Total number of inflammatory cells in the exudate was measured but no correlation between surface mobility and cell recruitment where found. However, the number of surface associated cells where significantly lower on the surfaces with high molecular mobility (PLMA and PBMA). The histological evaluation performed after 28 days revealed thicker fibrous capsule and a higher number of blood vessels on the low molecular mobility surface (PIBMA). After 28 days the cell activity was higher on the high molecular mobility surfaces (PLMA and PBMA) compared with PIBMA, based on the cytokine release. None of the surfaces induced any significant cell-death. On the basis of the results of this study we conclude that there is a significant difference in biological response to surfaces with different in molecular mobility. This might affect the wound healing process and the biocompatibility of biomaterials. © 2007 Wiley Periodicals, Inc.

  • Fit for the job? How corporeal expectations shape physical education teachers' understandings of content, pedagogy, and the purposes of physical education
  • 2021
  • Ingår i: Physical Education and Sport Pedagogy. - : Informa UK Limited. - 1740-8989 .- 1742-5786. ; 28:1, s. 29-42
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: People often expect physical education teachers to look fit and athletic, to do lots of physical activity, and to eat well. While ample research exists on physical education teachers' bodies, relatively few scholars have investigated how physical educators relate corporeal expectations to broader ideas about subject content, pedagogy, and the purposes of the school subject. Aim: The specific aim of the paper is to identify the assumptions about content, pedagogy, and educational purposes that teachers make when they talk about a perceived need for physical educators to look fit and athletic. Method: To frame our work theoretically, we draw from a Swedish didaktik of physical education tradition and employ Bakhtin's concept of speech genres, and Wertsch's concept of privileging. Our empirical material consists of transcripts generated from 6 focus group and 6 individual interviews (24 teachers in total, average age of 40 years, average teaching experience 11 years). Findings: Data suggest that when teachers use an 'athletic-looking teacher as healthy role model' speech genre, they tend to privilege: (1) a particular version of health as subject content that involves not being too overweight and maintaining physical functionality in sports. This content is based on biomedical conceptions of health which foreground exercise, eating and weight, and a pathogenic reduction of risk; (2) particular pedagogies in PE that put the teacher at the centre of the pedagogical situation, and; (3) a certain educational purpose in PE, which is to educate citizens for healthy lives through participation in sport. With respect to this purpose, increasing body weight enters the genre as a potential obstacle for educational success. Discussion: The findings raise questions concerning appropriate curricular content and its relation to teacher identities. They suggest that learning possibilities may be missed when certain content, pedagogies, and outcomes are privileged. The findings also indicate how wider voices are implicated in the speech genre. Conclusion: The paper is concluded with reflections on the possibility for change regarding expectations of physical education teachers' bodies and pedagogies.

    • Aim: To provide insight into how physical education teachers use discursive resources related to obesity to create particular professional identities.Method: Data come from focus group and individual interviews with physical education teachers in Sweden. Discourse theory on teacher identities frame the analysis of the empirical material.Results: Data suggest that teachers in Sweden make use of six distinct but related discursive contributions to produce three professional identities: the caring practitioner, an identity concerned with ensuring all pupils irrespective of size participate in physical education; the activity luminary, an identity that focuses on inspiring pupils toward activity across the lifespan, and; the body rationalist, an identity concerned with challenging unrealistic media discourses and reassuring pupils that they have “normal” bodies.Discussion: The identities appear more inclusive, sensitive, and critical than current physical education literature on obesity suggests, however they also contain elements that are fundamentally unsympathetic to overweight individuals.

  • In vivo interaction between biodegradable magnesium implants and soft tissue Part II: Kinetics of the cellular response at the host-implant interface
  • 2021
  • Ingår i: 13th Biometal Conference, 23-26 August 2021, Virtual Conference..

    • INTRODUCTION: Regenerative therapies often engage multiple tissues. Soft tissue complications (e.g. dehiscences and infection) may violate successful bone regeneration. Magnesium (Mg)-based degradable implants is a promising treatment alternative for musculoskeletal injuries, avoiding second-stage surgical removal. In several clinical applications, the implant is in contact with both the bone and the overlying soft tissue. Whereas the bone response to Mg implants has been a major research focus, less attention has been paid to the soft tissue response. The present study investigated the spatial and temporal molecular, cellular and structural events taking place at the soft tissue-Mg implant interface after in vivo implantation in an experimental rat model. METHODS: Following approval by the Local Ethical Committee at the University of Gothenburg (Dnr 02437/2018), female Sprague-Dawley rats (n=90) were implanted with discs manufactured from pure magnesium (99.99% - high purity; Mg) or from pure titanium (grade 4; Ti) (herein, employed as a control, possessing biocompatibility properties). Subcutaneous pockets were surgically created in the animal dorsum and were implanted with: 1- Ti; or 2- Mg discs; or 3- left without implants (Sham Ti or Sham Mg). After 1, 3, 6, 14 and 28 days, animals were euthanized, and three types of samples were retrieved: 1-Implants with the adherent cells (n=8/group/time-point): for cell counting and molecular gene expression of the implant-adherent cells. 2-Peri-implant exudate (n=8/group/time-point): for analyses of the number, type, viability, and gene expression of cells in the peri-implant space. 3-Peri-implant tissue with implants (n=8/group/time-point): enabling histological and histomorphometric analyses of soft tissue and fibrous capsule organization around the implant. Statistical comparisons were made between experimental groups at each time point and between time-points for each experimental group. (Kruskal-Wallis, Mann-Whitney and Wilcoxon signed-rank tests; p<0.05). RESULTS: Cells recruited to the exudates and adherent to the surface of the implants featured different kinetics between Mg and Ti groups. At the surface of Mg implant, the number of adherent cells sharply increased from 1 day to reach a peak at 6 days, thereafter decreasing toward 28 days. The ratio of implant-adherent/exudate cells was significantly higher at Mg vs Ti after 6 days, whereas the reverse was detected after 28 days. RNA extracted from cells from the different compartments revealed good quality, allowing detailed molecular analysis. After 28d, the fibrous capsule around Mg implants was significantly thinner than around Ti. CONCLUSIONS: In comparison to non-degradable Ti controls, soft tissue healing around biodegradable Mg implants is characterized by an early, intense, but yet transient, cellular influx in the immediate vicinity of the implant surface, and, at later stage, with a reduced fibrotic encapsulation.

    • The notion of Sweden as a secular nation-state, or rather the linkage between notions of secularism and gender equality, is strong in public discourse. Within this frame, religion is located in a traditional past and often understood as a hindrance to liberal and modern values.In this chapter we focus on our own situatedness as feminist researchers living in Sweden and thereby explore how, where and why ideologies of secularism entangled with notions of European values and superiority become dominant. Inspired by the feminist tradition of memory work, an aim is to explore the boundary between the secular and the religious through our own experiences and from our location in Sweden. The aim is also to search for counter-memories, both in the doing of secular (gendered) selves as well as the ongoing production of the “religious other”.

  • Determinants for choosing and adhering to active surveillance for localised prostate cancer: A nationwide population-based study
  • 2019

  • Tidskriftsartikel (refereegranskat)abstract
    • Objective Knowledge about factors influencing choice of and adherence to active surveillance (AS) for prostate cancer (PC) is scarce. We aim to identify which factors most affected choosing and adhering to AS and to quantify their relative importance. Design, setting and participants In 2015, we sent a questionnaire to all Swedish men aged ≤70 years registered in the National Prostate Cancer Register of Sweden who were diagnosed in 2008 with low-risk PC and had undergone prostatectomy, radiotherapy or started on AS. Outcome measurements and statistical analysis Logistic regression was used to calculate ORs with 95% CIs for factors potentially affecting choice and adherence to AS. Results 1288 out of 1720 men (75%) responded, 451 (35%) chose AS and 837 (65%) underwent curative treatment. Of those starting on AS, 238 (53%) diverted to treatment within 7years. Most men (83%) choose AS because ‘My doctor recommended AS’. Factors associated with choosing AS over treatment were older age (OR 1.81, 95%CI 1.29 to 2.54), a Charlson Comorbidity Index >2 (OR 1.50, 95%CI 1.06 to 2.13), being unaccompanied when notified of the cancer diagnosis (OR 1.45, 95%CI 1.11 to 1.89). Men with a higher prostate-specific antigen (PSA) at the time of diagnosis were less likely to adhere to AS (OR 0.26, 95%CI 0.10 to 0.63). The reason for having treatment after initial AS was ‘the PSA level was rising’ in 55% and biopsy findings in 36%. Conclusions A doctor’s recommendation strongly affects which treatment is chosen for men with low-risk PC. Rising PSA values were the main factor for initiating treatment for men on AS. These findings need be considered by healthcare providers who wish to increase the uptake of and adherence to AS.

    • Background: Information about how men with prostate cancer (PC) experience their medical care and factors associated with their overall satisfaction with care (OSC) is limited. Objective: To investigate OSC and factors associated with OSC among men with low-risk PC. Design, setting, and participants: Men registered in the National Prostate Cancer Register of Sweden as diagnosed in 2008 with low-risk PC at the age of ≤70 yr who had undergone radical prostatectomy (RP), radiotherapy (RT), or started on active surveillance (AS) were invited in 2015 to participate in this nationwide population-based survey (n = 1720). Outcome measurements and statistical analysis: OSC data were analysed using ordinal logistic regression. Odds ratios (ORs) were calculated for comparisons between the highest and lowest possible response categories. Results and limitations: A total of 1288 men (74.9%) responded. High OSC was reported by 958 (74.4%). Factors associated with high OSC were high participation in decision-making (OR 4.18, 95% confidence interval [CI] 2.61–6.69), receiving more information (OR 11.1, 95% CI 7.97–15.6), high-quality information (OR 7.85, 95% CI 5.46–11.3), access to a nurse navigator (OR 1.80, 95% CI 1.44–2.26), and better functional outcomes (defined as 25 points higher on the EPIC-26 questionnaire; OR 1.34, 95% CI 1.21–1.48). OSC was not affected by whether a doctor or specialist nurse conducted follow-up (OR 0.84, 95% CI 0.66–1.07). These findings were similar across treatment groups. Men who had undergone RP or RT reported high OSC more often than men on AS (78.2% vs 84.0% vs 72.6%), high participation in decision-making (70.5% vs 64.5% vs 49.2%), and having received more information (40.5% vs 45.8% vs 28.6%), and were less likely to believe they would die from PC (3.8% vs 3.9% vs 8.0%). Limitations include the nonrandomised retrospective design and potential recall bias. Conclusions: Information and participation in decision-making, as well as access to a nurse navigator, are key factors for OSC, regardless of treatment. Men on AS need more information about their treatment and need to participate more in decision-making. OSC was as high among men who had nurse-led follow-up as among men who had doctor-led follow-up. Patient summary: Information about how men with low-risk prostate cancer experience their medical care is limited. In this nationwide population-based study we found that information and participation in decision-making as well as access to a nurse navigator are key factors for satisfaction regardless of treatment. Men who are being closely watched for prostate cancer without immediate curative treatment need more information than they now receive and need to participate more in decision-making than they currently do. Information and participation in decision-making are key factors for satisfaction with care among men with localised prostate cancer. Men under active surveillance need more information about their treatment and need to participate more in decision-making. © 2018 European Association of Urology

    • BackgroundRadical prostatectomy reduces mortality among men with localized prostate cancer; however, important questions regarding long-term benefit remain. MethodsBetween 1989 and 1999, we randomly assigned 695 men with early prostate cancer to watchful waiting or radical prostatectomy and followed them through the end of 2012. The primary end points in the Scandinavian Prostate Cancer Group Study Number 4 (SPCG-4) were death from any cause, death from prostate cancer, and the risk of metastases. Secondary end points included the initiation of androgen-deprivation therapy. ResultsDuring 23.2 years of follow-up, 200 of 347 men in the surgery group and 247 of the 348 men in the watchful-waiting group died. Of the deaths, 63 in the surgery group and 99 in the watchful-waiting group were due to prostate cancer; the relative risk was 0.56 (95% confidence interval [CI], 0.41 to 0.77; P=0.001), and the absolute difference was 11.0 percentage points (95% CI, 4.5 to 17.5). The number needed to treat to prevent one death was 8. One man died after surgery in the radical-prostatectomy group. Androgen-deprivation therapy was used in fewer patients who underwent prostatectomy (a difference of 25.0 percentage points; 95% CI, 17.7 to 32.3). The benefit of surgery with respect to death from prostate cancer was largest in men younger than 65 years of age (relative risk, 0.45) and in those with intermediate-risk prostate cancer (relative risk, 0.38). However, radical prostatectomy was associated with a reduced risk of metastases among older men (relative risk, 0.68; P=0.04). ConclusionsExtended follow-up confirmed a substantial reduction in mortality after radical prostatectomy; the number needed to treat to prevent one death continued to decrease when the treatment was modified according to age at diagnosis and tumor risk. A large proportion of long-term survivors in the watchful-waiting group have not required any palliative treatment. (Funded by the Swedish Cancer Society and others.) The randomized Swedish trial of prostatectomy versus watchful waiting in disease detected mainly clinically (not by PSA screening) continues to show a benefit for early prostatectomy. The number of men younger than 65 needed to treat to prevent one death is now four. The Scandinavian Prostate Cancer Group Study Number 4 (SPCG-4), a randomized trial of radical prostatectomy versus watchful waiting in men with localized prostate cancer diagnosed before the era of prostate-specific antigen (PSA) testing, showed a survival benefit of radical prostatectomy as compared with observation at 15 years of follow-up.(1) By contrast, the Prostate Cancer Intervention versus Observation Trial (PIVOT), initiated in the early era of PSA testing, showed that radical prostatectomy did not significantly reduce prostate cancer-specific or overall mortality after 12 years.(2) PSA screening profoundly changes the clinical domain of study. Among other considerations, the substantial additional lead time ...

    • BACKGROUND Radical prostatectomy reduces mortality among men with clinically detected localized prostate cancer, but evidence from randomized trials with long-term followup is sparse. METHODS We randomly assigned 695 men with localized prostate cancer to watchful waiting or radical prostatectomy from October 1989 through February 1999 and collected follow-up data through 2017. Cumulative incidence and relative risks with 95% confidence intervals for death from any cause, death from prostate cancer, and metastasis were estimated in intention-to-treat and per-protocol analyses, and numbers of years of life gained were estimated. We evaluated the prognostic value of histopathological measures with a Cox proportional-hazards model. RESULTS By December 31, 2017, a total of 261 of the 347 men in the radical-prostatectomy group and 292 of the 348 men in the watchful-waiting group had died; 71 deaths in the radical-prostatectomy group and 110 in the watchful-waiting group were due to prostate cancer (relative risk, 0.55; 95% confidence interval [CI], 0.41 to 0.74; P<0.001; absolute difference in risk, 11.7 percentage points; 95% CI, 5.2 to 18.2). The number needed to treat to avert one death from any cause was 8.4. At 23 years, a mean of 2.9 extra years of life were gained with radical prostatectomy. Among the men who underwent radical prostatectomy, extracapsular extension was associated with a risk of death from prostate cancer that was 5 times as high as that among men without extracapsular extension, and a Gleason score higher than 7 was associated with a risk that was 10 times as high as that with a score of 6 or lower (scores range from 2 to 10, with higher scores indicating more aggressive cancer). CONCLUSIONS Men with clinically detected, localized prostate cancer and a long life expectancy benefited from radical prostatectomy, with a mean of 2.9 years of life gained. A high Gleason score and the presence of extracapsular extension in the radical prostatectomy specimens were highly predictive of death from prostate cancer.

  • RED, PEF, and EPD: Conflicting rules for determining the carbon footprint of biofuels give unclear signals to fuel producers and customers
  • 2022
  • Ingår i: Frontiers in Climate. - : Frontiers Media SA. - 2624-9553. ; 4
  • Tidskriftsartikel (refereegranskat)abstract
    • Biofuel producers and other commodity suppliers are increasingly affected by conflicting rules for life cycle assessment (LCA). They may get multiple requests for LCAs to be used in various contexts, which require the application of different methodological approaches that vary in scope, system boundaries, data demand, and more. This results in increased cost and competence requirements for producers, as well as confusion among other actors including their customers. Differences in methodologies might also lead to various outcomes, conclusions and conflicting guidance regarding which fuels to prioritize or develop. We have analyzed the actual differences when applying three different frameworks: the EU Renewable Energy Directive (RED), the EU framework for Product Environmental Footprints (PEF), and the framework of Environmental Product Declarations (EPD), which have different modeling requirements. We analyzed the methods from a conceptual point of view and also applied the methods to estimate the carbon footprint on a wide range of biofuel production pathways: (i) ethanol from corn, (ii) fatty acid methyl ester (FAME) from rapeseed oil, (iii) biogas from food waste, (iv) hydrogenated vegetable oil (HVO) from rapeseed oil, and (v) HVO from used cooking oil. Results obtained for a specific fuel could differ substantially depending on the framework applied and the assumptions and interpretations made when applying the different frameworks. Particularly, the results are very sensitive to the modeling of waste management when biofuel is produced from waste. Our results indicate a much higher climate impact for, e.g., biogas and HVO produced from used cooking oil when assessed with the PEF framework compared to the other frameworks. This is because PEF assigns at least part of the production of primary materials and energy to the use of recycled material and recovered energy. Developing Category Rules for biofuels for PEF and EPD ought to help clarifying remaining ambiguities.

  • Methylmercury-induced DNA methylation—From epidemiological observations to experimental evidence
  • 2022
  • Ingår i: Frontiers in Genetics. - : Frontiers Media SA. - 1664-8021. ; 13
  • Tidskriftsartikel (refereegranskat)abstract
    • Methylmercury (MeHg) is a developmental neurotoxicant, and one potential mechanism of MeHg toxicity is epigenetic dysregulation. In a recent meta-analysis of epigenome-wide association studies (EWAS), associations between prenatal MeHg exposure and DNA methylation at several genomic sites were identified in blood from newborns and children. While EWASs reveal human-relevant associations, experimental studies are required to validate the relationship between exposure and DNA methylation changes, and to assess if such changes have implications for gene expression. Herein, we studied DNA methylation and gene expression of five of the top genes identified in the EWAS meta-analysis, MED31, MRPL19, GGH, GRK1, and LYSMD3, upon MeHg exposure in human SH-SY5Y cells exposed to 8 or 40 nM of MeHg during differentiation, using bisulfite-pyrosequencing and qPCR, respectively. The concentrations were selected to cover the range of MeHg concentrations in cord blood (2–8.5 μg/L) observed in the cohorts included in the EWAS. Exposure to MeHg increased DNA methylation at MED31, a transcriptional regulator essential for fetal development. The results were in concordance with the epidemiological findings where more MED31 methylation was associated with higher concentrations of MeHg. Additionally, we found a non-significant decrease in DNA methylation at GGH, which corresponds to the direction of change observed in the EWAS, and a significant correlation of GGH methylation with its expression. In conclusion, this study corroborates some of the EWAS findings and puts forward candidate genes involved in MeHg’s effects on the developing brain, thus highlighting the value of experimental validation of epidemiological association studies.

    • OBJECTIVES: To evaluate the early cellular attachment and viability to modified polyethylene glycol (PEG) hydrogels with the influence of arginine-glycine-aspartic acid (RGD) in an in vitro model system. MATERIAL AND METHODS: Human gingival fibroblasts (HGF-1) were cultured on 6 different modalities of PEG hydrogel in hydrophobic polystyrene wells. A total of 7500cells/well (10000cells/cm(2) ) were dispersed over the PEG filled wells and incubated in triplicates for 24h, 7 and 13days. Cell numbers were calculated by means of a NucleoCounter. Cell viability was determined by measuring lactate dehydrogenase (LDH). For statistical analysis, nonparametric Kruska-Wallis test followed by Dunetts T3 test were used. RESULTS: All PEG modifications showed good biocompatibility, as demonstrated by low LDH values per cell at the earlier two time points. After 13days, all PEG modifications showed significantly lower number of cells compared with the controls, and the MX60 configurations demonstrated significantly higher LDH/cell values compared with the other hydrogels. CONCLUSIONS: Modifications of the physio-chemical properties of PEG hydrogels and the addition of RGD and spacers influenced the initial cellular response of cultured HGF-1 cells. With the exception of MX60 after 13days, all PEG formulations performed similarly well. Early cellular response should be considered when developing PEG-based material for clinical purposes.

  • Decoding of the surfaceome and endocytome in primary glioblastoma cells identifies potential target antigens in the hypoxic tumor niche
  • 2024
  • Ingår i: Acta Neuropathologica Communications. - : BioMed Central (BMC). - 2051-5960. ; 12:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Immunotherapies with antibody-drug-conjugates (ADC) and CAR-T cells, targeted at tumor surface antigens (surfaceome), currently revolutionize clinical oncology. However, target identification warrants a better understanding of the surfaceome and how it is modulated by the tumor microenvironment. Here, we decode the surfaceome and endocytome and its remodeling by hypoxic stress in glioblastoma (GBM), the most common and aggressive brain tumor in adults. We employed a comprehensive approach for global and dynamic profiling of the surfaceome and endocytosed (endocytome) proteins and their regulation by hypoxia in patient-derived GBM cultures. We found a heterogeneous surface-endocytome profile and a divergent response to hypoxia across GBM cultures. We provide a quantitative ranking of more than 600 surface resident and endocytosed proteins, and their regulation by hypoxia, serving as a resource to the cancer research community. As proof-of-concept, the established target antigen CD44 was identified as a commonly and abundantly expressed surface protein with high endocytic activity. Among hypoxia induced proteins, we reveal CXADR, CD47, CD81, BSG, and FXYD6 as potential targets of the stressed GBM niche. We could validate these findings by immunofluorescence analyses in patient tumors and by increased expression in the hypoxic core of GBM spheroids. Selected candidates were finally confronted by treatment studies, showing their high capacity for internalization and ADC delivery. Importantly, we highlight the limited correlation between transcriptomics and proteomics, emphasizing the critical role of membrane protein enrichment strategies and quantitative mass spectrometry. Our findings provide a comprehensive understanding of the surface-endocytome and its remodeling by hypoxia in GBM as a resource for exploration of targets for immunotherapeutic approaches in GBM.

  • Ingår i: International journal of nanomedicine. - : Informa UK Limited. - 1176-9114 .- 1178-2013. ; 9:1, s. 2499-2515
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Patterning medical devices at the nanoscale level enables the manipulation of cell behavior and tissue regeneration, with topographic features recognized as playing a significant role in the osseointegration of implantable devices. Methods: In this study, we assessed the ability of titanium-coated hemisphere-like topographic nanostructures of different sizes (approximately 50, 100, and 200 nm) to influence the morphology, proliferation, and osteogenic differentiation of human mesenchymal stem cells (hMSCs). Results: We found that the proliferation and osteogenic differentiation of hMSCs was influenced by the size of the underlying structures, suggesting that size variations in topographic features at the nanoscale level, independently of chemistry, can be exploited to control hMSC behavior in a size-dependent fashion. Conclusion: Our studies demonstrate that colloidal lithography, in combination with coating technologies, can be exploited to investigate the cell response to well defined nanoscale topography and to develop next-generation surfaces that guide tissue regeneration and promote implant integration.

  • Risk for Behavioral Problems Independent of Cognitive Functioning in Children Born at Low Gestational Ages
  • 2020
  • Ingår i: Frontiers in Pediatrics. - : Frontiers Media S.A.. - 2296-2360. ; 8:311
  • Tidskriftsartikel (refereegranskat)abstract
    • This study aimed to investigate cognitive and behavioral outcomes in relation to gestational age (GA) in school-aged children born preterm (PT). Results from the Wechsler Intelligence Scale for Children, 4th edition (WISC-IV), and the Child Behavior Checklist (CBCL) were analyzed in 51 children (mean age: 7.8 years [range: 7.0–8.7]) born PT (mean GA: 31 weeks [range: 23–35]; birth weight, mean: 1,637 g [range:404–2,962]) with the majority (96%) having no diagnosed cognitive, sensory, or motor impairments. The control group included 57 age-matched typically developing children (mean age: 7.9 years [range: 6.2–8.7]) born full-term (FT). Children born PT, extremelyPT (GA < 28) in particular, showed significantly lower cognitive performance and higher behavioral problem scores compared with children born FT. GA was found to predict aspects of both cognitive functioning and behavioral problems within the PT group, with lower GA being related to both poorer cognitive outcomes and elevated affective and attention-deficit/hyperactivity problems. Global cognitive functioning did not independently predict aspects of behavioral outcomes. Findings demonstrate that, even in children born PT without severe perinatal and/or postnatal complications and receiving active perinatal care, a short gestation is an evident risk factor for long-term negative effects on mental health independent of cognitive functioning. Additional findings suggest that both reduced growth and lower parental educational level may contribute to increased risk for poorer cognitive and behavioral functioning in children born PT.

  • Depletion of ATP and glucose in advanced human atherosclerotic plaques
  • 2017
  • Ingår i: PLoS One. - : Public Library of Science (PLoS). - 1932-6203. ; 12:6
  • Tidskriftsartikel (refereegranskat)abstract
    • Severe hypoxia develops close to the necrotic core of advanced human atherosclerotic plaques, but the energy metabolic consequences of this hypoxia are not known. In animal models, plaque hypoxia is also associated with depletion of glucose and ATP. ATP depletion may impair healing of plaques and promote necrotic core expansion. To investigate if ATP depletion is present in human plaques, we analyzed the distribution of energy metabolites (ATP, glucose, glycogen and lactate) in intermediate and advanced human plaques.Snap frozen carotid endarterectomies from 6 symptomatic patients were analyzed. Each endarterectomy included a large plaque ranging from the common carotid artery (CCA) to the internal carotid artery (ICA). ATP, glucose, and glycogen concentrations were lower in advanced (ICA) compared to intermediate plaques (CCA), whereas lactate concentrations were higher. The lowest concentrations of ATP, glucose and glycogen were detected in the perinecrotic zone of advanced plaques.Our study demonstrates severe ATP depletion and glucose deficiency in the perinecrotic zone of human advanced atherosclerotic plaques. ATP depletion may impair healing of plaques and promote disease progression.

  • Guided bone regeneration using resorbable membrane and different bone substitutes : Early histological and molecular events
  • 2016
  • Ingår i: Acta Biomaterialia. - : Elsevier BV. - 1742-7061 .- 1878-7568. ; 29, s. 409-423
  • Tidskriftsartikel (refereegranskat)abstract
    • Bone insufficiency remains a major challenge for bone-anchored implants. The combination of guided bone regeneration (GBR) and bone augmentation is an established procedure to restore the bone. However, a proper understanding of the interactions between the bone substitute and GBR membrane materials and the bone-healing environment is lacking. This study aimed to investigate the early events of bone healing and the cellular activities in response to a combination of GBR membrane and different calcium phosphate (CaP) materials. Defects were created in the trabecular region of rat femurs, and filled with deproteinized bovine bone (DBB), hydroxyapatite (HA) or strontium-doped HA (SrHA) or left empty (sham). All the defects were covered with an extracellular matrix membrane. Defects were harvested after 12 h, 3 d and 6 d for histology/histomorphometry, immunohistochemistry and gene expression analyses. Histology revealed new bone, at 6 d, in all the defects. Larger amount of bone was observed in the SrHA-filled defect. This was in parallel with the reduced expression of osteoclastic genes (CR and CatK) and the osteoblast-osteoclast coupling gene (RANKL) in the SrHA defects. Immunohistochemistry indicated fewer osteoclasts in the SrHA defects. The observations of CD68 and periostin-expressing cells in the membrane per se indicated that the membrane may contribute to the healing process in the defect. It is concluded that the bone-promoting effects of Sr in vivo are mediated by a reduction in catabolic and osteoblast-osteoclast coupling processes. The combination of a bioactive membrane and CaP bone substitute material doped with Sr may produce early synergistic effects during GBR. Statement of significance The study provides novel molecular, cellular and structural evidence on the promotion of early bone regeneration in response to synthetic strontium-containing hydroxyapatite (SrHA) substitute, in combination with a resorbable, guided bone regeneration (GBR) membrane. The prevailing view, based mainly upon in vitro data, is that the beneficial effects of Sr are exerted by the stimulation of bone-forming cells (osteoblasts) and the inhibition of bone-resorbing cells (osteoclasts). In contrast, the present study demonstrates that the local effect of Sr in vivo is predominantly via the inhibition of osteoclast number and activity and the reduction of osteoblast-osteoclast coupling. This experimental data will form the basis for clinical studies, using this material as an interesting bone substitute for guided bone regeneration.

  • Tumor cure probability during alpha-RIT of ovarian cancer with different radiation sensitivity.
  • 2010
  • Ingår i: Anticancer research. - 1791-7530. ; 30:7, s. 2545-2551
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: To calculate the tumor cure probability (TCP) and metastatic cure probability (MCP) during alpha-radioimmunotherapy (alpha-RIT) of small ovarian cancer tumors with cells of different radiation sensitivity. MATERIALS AND METHODS: An in-house-developed biokinetic model and a Monte-Carlo program were used to calculate the cumulative activity on tumor cell surfaces and the specific energy to tumor cell nuclei, respectively. An in-house-developed computational model was used to calculate the TCP and MCP as a function of assumed radiation sensitivities, expressed as D(37), of the tumor cells. The calculations were performed using various assumptions regarding the activity distribution in measured tumors and used the alpha-particle energies emitted from astatine-211 ((211)At). Regarding the calculations of the cumulative activity on each cell surface, the number of antigenic sites expressed by NIH:OVCAR-3 cells for the mAb MX35 F(ab')2 was used. To illustrate the tumor growth at the peritoneum in nude mice, scanning electron microscopy images were used. RESULTS: In the case of a maximum diffusion depth of 30 mum for the activity in the tumors, the TCP was high for D(37) values not exceeding approximately 4.3, approximately 2.9, approximately 1.8, and approximately 0.8 Gy for 200, 100, 50, and 25 kBq (211)At-MX35 F(ab')2 four weeks after cell inoculation, respectively. In order to achieve complete remission of the metastatic disease in mice (i.e. MCP=1), the D(37) value should not exceed approximately 2.2, approximately 1.3, approximately 0.6, and approximately 0.3 Gy when injecting 200, 100, 50, or 25 kBq, respectively, assuming a maximum diffusion depth of 30 mum for the activity in the tumors. CONCLUSION: The radiation sensitivity, expressed as D(37), of tumor cells subjected to alpha-RIT could be decisive for therapeutic outcome, expressed as TCP or MCP, when treating small tumors of ovarian cancer.

  • Prostate-specific antigen levels as a predictor of lethal prostate cancer
  • 2007
  • Ingår i: Journal of the National Cancer Institute. - Oxford : Oxford Univ. Press. - 0027-8874 .- 1460-2105. ; 99:7, s. 526-532
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Rates of long-term survival among patients with untreated localized prostate cancer are high. To avoid unnecessary treatment, tools are needed to identify the small proportion of patients who are destined to develop lethal prostate cancer. Methods: To evaluate the accuracy of early changes in prostate-specific antigen (PSA) levels as predictors of prostate cancer outcome, we assessed serial measurements of PSA level among 267 men with localized prostate cancer in a Scandinavian cohort of men who were diagnosed between 1989 and 1999 and who were managed by watchful waiting. We then 1) fitted individual regression lines to the PSA values assessed for each patient during the first 2 years of follow-up by using three different models, 2) evaluated early PSA curve characteristics as determinants of the cumulative incidence of lethal prostate cancer and calculated hazard ratios for baseline PSA value and rate of change in PSA level to prostate cancer outcome, and 3) plotted time-dependent receiver operating characteristic (ROC) curves. All P values are two-sided. Results: During complete follow-up for a mean of 8.5 years, 34 patients (13%) died from prostate cancer, and 18 (7%) developed metastases but were still alive at end of follow-up. In a log-linear model, both PSA value at baseline (P = .05) and the rate of PSA change (P<.001) were associated with the development of lethal prostate cancer. In the ROC analysis, however, the accuracy of classifying the disease as either indolent or destined to progress was low, regardless of the cut point chosen for initial PSA level or rate of change in PSA level. Conclusions: Although baseline PSA value and rate of PSA change are prognostic factors for lethal prostate cancer, they are poor predictors of lethal prostate cancer among patients with localized prostate cancer who are managed by watchful waiting.

  • Konferensbidrag (refereegranskat)abstract
    • The purpose is to identify, through a simulation study, how the size of the extra safety stock needed when transferring production vary with uncertainties introduced by the transfer. The study shows that there is a substantial uncertainty increase during production transfer, related to the uncertainty of time to reach steady state. Learning curve factors have the largest impact, while the effects for the production yield factors are about of half their size, but still considerably large in relation to the regular safety stock. The study contributes by structuring the decision problem and indicating the importance of various uncertainties.

  • Läslyftet i praktiken : en pilotstudie inför ett större projekt
  • 2016
  • Ingår i: SMDI 12 TEXTKULTURER.
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Inför ett större projekt med syfte att utifrån Läslyftet med dess fokus på läs- och skrivrelaterade frågor undersöka lärares kompetensutveckling och hur den realiseras i undervisningspraktiken, genomför vi under ht- 16 ett pilotprojekt. I en gymnasieskola följer vi under höstterminens inledning ett lärarlags arbete med Läslyftet. Det empiriska materialet samlas in genom observationer av de kollegiala samtalen och av hur de läslyftsgenererade undervisningsaktiviteterna iscensätts. Detta kompletteras av intervjuer med deltagarna. Därtill analyseras det material som finns i den aktuella modulen. I pilotstudien aktualiseras några av frågeställningarna från vårt planerade forskningsprojekt, nämligen vilka föreställningar om kunskap, lärande och läs- och skrivundervisning som kommer till uttryck i modulinnehållet samt hur dessa rekontextualiseras i lärarnas samtal. Dessutom undersöks iscensättningen av de läslyftsgenererade aktiviteterna i undervisningspraktiken i relation till de kollegiala samtalen och intervjuerna med lärarna.Studiens teoriram utgörs av ett sociokulturellt perspektiv på lärande (Säljö, 2010; Wertsch, 1998) och teorier om lärares kompetensutveckling och lärande (Timperley m.fl., 2007; Vescio m.fl., 2008; Stoll m.fl., 2008; Wermke, 2013; Langelotz, 2013). För dokumentation används ljud- och filmupptagning tillsammans med observationsanteckningar. Analyserna inspireras av tematisk textanalys (Braun & Clarke, 2008; Boyatzis, 1998) och aktivitetsteori (Engeström, 1987; Engeström & Sannino, 2010). I presentationen redogörs för de första analyserna och en diskussion förs om hur erfarenheterna från dessa, tillsammans med resultat från en tidigare genomförd (ännu inre publicerad) studie, kan användas i relation till det planerade projektet.
