Journal article (peer-reviewed)abstract
- Being taller is associated with enhanced longevity, and higher education and earnings. We reanalysed 1472 population-based studies, with measurement of height on more than 18.6 million participants to estimate mean height for people born between 1896 and 1996 in 200 countries. The largest gain in adult height over the past century has occurred in South Korean women and Iranian men, who became 20.2 cm (95% credible interval 17.522.7) and 16.5 cm (13.319.7) taller, respectively. In contrast, there was little change in adult height in some sub-Saharan African countries and in South Asia over the century of analysis. The tallest people over these 100 years are men born in the Netherlands in the last quarter of 20th century, whose average heights surpassed 182.5 cm, and the shortest were women born in Guatemala in 1896 (140.3 cm; 135.8144.8). The height differential between the tallest and shortest populations was 19-20 cm a century ago, and has remained the same for women and increased for men a century later despite substantial changes in the ranking of countries.

Effects of diabetes definition on global surveillance of diabetes prevalence and diagnosis: a pooled analysis of 96 population-based studies with 331288 participants
- 2015
-
In: The Lancet Diabetes & Endocrinology. - 2213-8595 .- 2213-8587. ; 3:8, s. 624-637
-
Journal article (peer-reviewed)abstract
- Background Diabetes has been defined on the basis of different biomarkers, including fasting plasma glucose (FPG), 2-h plasma glucose in an oral glucose tolerance test (2hOGTT), and HbA(1c). We assessed the effect of different diagnostic definitions on both the population prevalence of diabetes and the classification of previously undiagnosed individuals as having diabetes versus not having diabetes in a pooled analysis of data from population-based health examination surveys in different regions. Methods We used data from 96 population-based health examination surveys that had measured at least two of the biomarkers used for defining diabetes. Diabetes was defined using HbA(1c) (HbA(1c) >= 6 . 5% or history of diabetes diagnosis or using insulin or oral hypoglycaemic drugs) compared with either FPG only or FPG-or-2hOGTT definitions (FPG >= 7 . 0 mmol/L or 2hOGTT >= 11 . 1 mmol/L or history of diabetes or using insulin or oral hypoglycaemic drugs). We calculated diabetes prevalence, taking into account complex survey design and survey sample weights. We compared the prevalences of diabetes using different definitions graphically and by regression analyses. We calculated sensitivity and specificity of diabetes diagnosis based on HbA1c compared with diagnosis based on glucose among previously undiagnosed individuals (ie, excluding those with history of diabetes or using insulin or oral hypoglycaemic drugs). We calculated sensitivity and specificity in each survey, and then pooled results using a random-effects model. We assessed the sources of heterogeneity of sensitivity by meta-regressions for study characteristics selected a priori. Findings Population prevalence of diabetes based on FPG- or-2hOGTT was correlated with prevalence based on FPG alone (r= 0 . 98), but was higher by 2-6 percentage points at different prevalence levels. Prevalence based on HbA(1c) was lower than prevalence based on FPG in 42 . 8% of age-sex-survey groups and higher in another 41 . 6%; in the other 15 . 6%, the two definitions provided similar prevalence estimates. The variation across studies in the relation between glucose-based and HbA(1c)-based prevalences was partly related to participants' age, followed by natural logarithm of per person gross domestic product, the year of survey, mean BMI, and whether the survey population was national, subnational, or from specific communities. Diabetes defined as HbA(1c) 6 . 5% or more had a pooled sensitivity of 52 . 8% (95% CI 51 . 3-54 . 3%) and a pooled specificity of 99 . 74% (99 . 71-99 . 78%) compared with FPG 7 . 0 mmol/L or more for diagnosing previously undiagnosed participants; sensitivity compared with diabetes defined based on FPG-or-2hOGTT was 30 . 5% (28 . 7-32 . 3%). None of the preselected study-level characteristics explained the heterogeneity in the sensitivity of HbA(1c) versus FPG. Interpretation Different biomarkers and definitions for diabetes can provide different estimates of population prevalence of diabetes, and differentially identify people without previous diagnosis as having diabetes. Using an HbA(1c)-based definition alone in health surveys will not identify a substantial proportion of previously undiagnosed people who would be considered as having diabetes using a glucose-based test.

Worldwide trends in diabetes since 1980: A pooled analysis of 751 population-based studies with 4.4 million participants
- 2016
-
In: The Lancet. - : Elsevier B.V.. - 0140-6736 .- 1474-547X. ; 387:10027, s. 1513-1530
-
Journal article (peer-reviewed)abstract
- Background: One of the global targets for non-communicable diseases is to halt, by 2025, the rise in the age standardised adult prevalence of diabetes at its 2010 levels. We aimed to estimate worldwide trends in diabetes, how likely it is for countries to achieve the global target, and how changes in prevalence, together with population growth and ageing, are aff ecting the number of adults with diabetes.Methods: We pooled data from population-based studies that had collected data on diabetes through measurement of its biomarkers. We used a Bayesian hierarchical model to estimate trends in diabetes prevalence-defined as fasting plasma glucose of 7.0 mmol/L or higher, or history of diagnosis with diabetes, or use of insulin or oral hypoglycaemic drugs-in 200 countries and territories in 21 regions, by sex and from 1980 to 2014. We also calculated the posterior probability of meeting the global diabetes target if post-2000 trends continue.Findings: We used data from 751 studies including 4372000 adults from 146 of the 200 countries we make estimates for. Global age-standardised diabetes prevalence increased from 4.3% (95% credible interval 2.4-17.0) in 1980 to 9.0% (7.2-11.1) in 2014 in men, and from 5.0% (2.9-7.9) to 7.9% (6.4-9.7) in women. The number of adults with diabetes in the world increased from 108 million in 1980 to 422 million in 2014 (28.5% due to the rise in prevalence, 39.7% due to population growth and ageing, and 31.8% due to interaction of these two factors). Age-standardised adult diabetes prevalence in 2014 was lowest in northwestern Europe, and highest in Polynesia and Micronesia, at nearly 25%, followed by Melanesia and the Middle East and north Africa. Between 1980 and 2014 there was little change in age-standardised diabetes prevalence in adult women in continental western Europe, although crude prevalence rose because of ageing of the population. By contrast, age-standardised adult prevalence rose by 15 percentage points in men and women in Polynesia and Micronesia. In 2014, American Samoa had the highest national prevalence of diabetes (>30% in both sexes), with age-standardised adult prevalence also higher than 25% in some other islands in Polynesia and Micronesia. If post-2000 trends continue, the probability of meeting the global target of halting the rise in the prevalence of diabetes by 2025 at the 2010 level worldwide is lower than 1% for men and is 1% for women. Only nine countries for men and 29 countries for women, mostly in western Europe, have a 50% or higher probability of meeting the global target.Interpretation: Since 1980, age-standardised diabetes prevalence in adults has increased, or at best remained unchanged, in every country. Together with population growth and ageing, this rise has led to a near quadrupling of the number of adults with diabetes worldwide. The burden of diabetes, both in terms of prevalence and number of adults aff ected, has increased faster in low-income and middle-income countries than in high-income countries.

The European Academy for Cognitive Behavioural Therapy for Insomnia : An initiative of the European Insomnia Network to promote implementation and dissemination of treatment
- 2020
-
In: Journal of Sleep Research. - : Wiley. - 0962-1105 .- 1365-2869. ; 29:2
-
Journal article (peer-reviewed)abstract
- Insomnia, the most prevalent sleep disorder worldwide, confers marked risks for both physical and mental health. Furthermore, insomnia is associated with considerable direct and indirect healthcare costs. Recent guidelines in the US and Europe unequivocally conclude that cognitive behavioural therapy for insomnia (CBT-I) should be the first-line treatment for the disorder. Current treatment approaches are in stark contrast to these clear recommendations, not least across Europe, where, if any treatment at all is delivered, hypnotic medication still is the dominant therapeutic modality. To address this situation, a Task Force of the European Sleep Research Society and the European Insomnia Network met in May 2018. The Task Force proposed establishing a European CBT-I Academy that would enable a Europe-wide system of standardized CBT-I training and training centre accreditation. This article summarizes the deliberations of the Task Force concerning definition and ingredients of CBT-I, preconditions for health professionals to teach CBT-I, the way in which CBT-I should be taught, who should be taught CBT-I and to whom CBT-I should be administered. Furthermore, diverse aspects of CBT-I care and delivery were discussed and incorporated into a stepped-care model for insomnia.

Fluctuating optimum and temporally variable selection on breeding date in birds and mammals
- 2020
-
In: Proceedings of the National Academy of Sciences of the United States of America. - : NATL ACAD SCIENCES. - 0027-8424 .- 1091-6490. ; 117:50, s. 31969-31978
-
Journal article (peer-reviewed)abstract
- Temporal variation in natural selection is predicted to strongly impact the evolution and demography of natural populations, with consequences for the rate of adaptation, evolution of plasticity, and extinction risk. Most of the theory underlying these predictions assumes a moving optimum phenotype, with predictions expressed in terms of the temporal variance and auto-correlation of this optimum. However, empirical studies seldom estimate patterns of fluctuations of an optimum phenotype, precluding further progress in connecting theory with observations. To bridge this gap, we assess the evidence for temporal variation in selection on breeding date by modeling a fitness function with a fluctuating optimum, across 39 populations of 21 wild animals, one of the largest compilations of long-term datasets with individual measurements of trait and fitness components. We find compelling evidence for fluctuations in the fitness function, causing temporal variation in the magnitude, but not the direction of selection. However, fluctuations of the optimum phenotype need not directly translate into variation in selection gradients, because their impact can be buffered by partial tracking of the optimum by the mean phenotype. Analyzing individuals that reproduce in consecutive years, we find that plastic changes track movements of the optimum phenotype across years, especially in bird species, reducing temporal variation in directional selection. This suggests that phenological plasticity has evolved to cope with fluctuations in the optimum, despite their currently modest contribution to variation in selection.

Efficacy of plain radiography and computer tomography in localizing the site of pelvic arterial bleeding in trauma patients
- 2010
-
In: Acta Radiologica. - : SAGE Publications. - 0284-1851 .- 1600-0455. ; 51:1, s. 107-16
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Immediate angiography is warranted in pelvic trauma patients with suspected arterial injury (AI) in order to stop ongoing bleeding. Prior to angiography, plain pelvic radiography (PPR) and abdominopelvic computer tomography (CT) are performed to identify fracture and hematoma sites. PURPOSE: To investigate if PPR and CT can identify the location of AI in trauma patients undergoing angiography. MATERIAL AND METHODS: 95 patients with pelvic fractures on PPR (29 women, 66 men), at a mean age of 44 (9-92) years, underwent pelvic angiography for suspected AI. Fifty-six of them underwent CT additionally. Right and left anterior and posterior fractures on PPR were registered, and fracture displacement was recorded for each quadrant. Arterial blush on CT was registered, and the size of the hematoma in each region was measured in cm(2). AIs were registered for anterior and posterior segments of both internal iliac arteries. Presence of fractures, arterial blush, and hematomas were correlated with AI. RESULTS: Presence of fracture in the corresponding skeletal segment on PPR showed sensitivity and specificity of 0.86 and 0.58 posteriorly, and 0.87 and 0.44 anteriorly. The area under the curve (AUC) was 0.77 and 0.69, respectively. Fracture displacement on PPR >0.9 cm posteriorly and >1.9 cm anteriorly revealed specificity of 0.84. Sensitivities of arterial blush and hematoma on CT were 0.38 and 0.82 posteriorly, and 0.24 and 0.82 anteriorly. The specificities were 0.96 and 0.58 posteriorly, and 0.79 and 0.53 anteriorly, respectively. For hematomas, the AUC was 0.79 posteriorly and 0.75 anteriorly. Size of hematoma >22 cm(2) posteriorly and >29 cm(2) anteriorly revealed specificity of 0.85 and 0.86, respectively. CONCLUSION: CT findings of arterial blush and hematoma predicted site of arterial bleeding on pelvic angiography. Also, PPR predicted the site of bleeding using location of fracture and size of displacement. In the hemodynamically unstable patient, PPR may contribute equally to effective assessment of injured arteries.

Gendered recognition practices and the perpetuation of vulnerability : A study in Swedish universities
- 2018
-
Conference paper (peer-reviewed)abstract
- In current critical research on work life in the higher education sector, analyses often revolve around neoliberal managerialism as contrasted to traditional professional academic values (cf. Henkel, 1997; Deem, 2004; Ekman et al, 2017). Academics are both faced with expectations to uphold the integrity of academic values in their research and teaching, whilst at the same time performing and ’careering’ in accordance with managerialist reforms (Clarke & Knights, 2015).Knights & Clarke (2014) analyse insecurity as a central aspect of identity in academics, conceptualizing academic life as a ‘bittersweet symphony’ populated by imposters (self- doubt and low self-esteem despite adequate performance), aspirants (under-recognised in relation to their inner sense of excellence) and existentialists (questioning the meaning of work and maintaining a sense of anxiety over their contributions to wider society). Another example is provided by Bristow et al (2017) who identify how early career-academics within CMS play on three narratives – diplomatic, combative and idealistic – by which they both resist and reproduce the ethos of business school neoliberalism in which they are embedded. Academics’ identity construction thus in different ways tend to position them as vulnerable selves (Cicmil et al, 2016), that is, as existentially exposed to the risks associated with projectified careers, macho-style management and a high degree of self-responsibility (Loveday, 2018).In addition, a number of earlier studies has also pointed out the highly gendered nature of how academic work is organized, how recruitment and promotion processes unfold etc. (cf. (cf. Hush, 2001; Mählck, 2003; van den Brink & Benschop, 2012).In this study we will focus on recognition practices (how recognition repeatedly tend to happen or not happen in local/cultural contexts, and thus also become the expectation on what may happen in future interactions) and their consequences for identity construction1and sense of vulnerability thus seem central to advance the above insights. Recognition practices thus involve not only what and whom is recognized or not for something, but also in what settings certain practices are legitimate or not, and how they are publicly displayed in social interaction.We suggest thatrecognition practices are an important yet under-researched aspect of academicidentity construction processesrecognition practices are gendered, i.e. we perform gender in our ways of- conferring and receiving recognition,- constructing what recognition may mean in different local/cultural contexts, - constructing when it is to be conferred/received or not,- constructing how it is appropriately played out how in social interaction.recognition practices tend to sustain vulnerability among academics, but in different ways for men and women.

Heterogeneity of breast cancer associations with five susceptibility loci by clinical and pathological characteristics
- 2008
-
In: PLoS genetics. - : Public Library of Science (PLoS). - 1553-7404. ; 4:4, s. e1000054-
-
Journal article (peer-reviewed)abstract
- A three-stage genome-wide association study recently identified single nucleotide polymorphisms (SNPs) in five loci (fibroblast growth receptor 2 (FGFR2), trinucleotide repeat containing 9 (TNRC9), mitogen-activated protein kinase 3 K1 (MAP3K1), 8q24, and lymphocyte-specific protein 1 (LSP1)) associated with breast cancer risk. We investigated whether the associations between these SNPs and breast cancer risk varied by clinically important tumor characteristics in up to 23,039 invasive breast cancer cases and 26,273 controls from 20 studies. We also evaluated their influence on overall survival in 13,527 cases from 13 studies. All participants were of European or Asian origin. rs2981582 in FGFR2 was more strongly related to ER-positive (per-allele OR (95%CI) = 1.31 (1.27-1.36)) than ER-negative (1.08 (1.03-1.14)) disease (P for heterogeneity = 10(-13)). This SNP was also more strongly related to PR-positive, low grade and node positive tumors (P = 10(-5), 10(-8), 0.013, respectively). The association for rs13281615 in 8q24 was stronger for ER-positive, PR-positive, and low grade tumors (P = 0.001, 0.011 and 10(-4), respectively). The differences in the associations between SNPs in FGFR2 and 8q24 and risk by ER and grade remained significant after permutation adjustment for multiple comparisons and after adjustment for other tumor characteristics. Three SNPs (rs2981582, rs3803662, and rs889312) showed weak but significant associations with ER-negative disease, the strongest association being for rs3803662 in TNRC9 (1.14 (1.09-1.21)). rs13281615 in 8q24 was associated with an improvement in survival after diagnosis (per-allele HR = 0.90 (0.83-0.97). The association was attenuated and non-significant after adjusting for known prognostic factors. Our findings show that common genetic variants influence the pathological subtype of breast cancer and provide further support for the hypothesis that ER-positive and ER-negative disease are biologically distinct. Understanding the etiologic heterogeneity of breast cancer may ultimately result in improvements in prevention, early detection, and treatment.

Insomnia as a predictor of mental disorders : A systematic review and meta-analysis
- 2019
-
In: Sleep Medicine Reviews. - : Elsevier BV. - 1087-0792 .- 1532-2955. ; 43, s. 96-105
-
Research review (peer-reviewed)abstract
- Previous research has identified insomnia as a predictor for the onset of depression. The aim of this meta-analysis is to investigate whether insomnia also predicts the onset of other mental disorders. Longitudinal studies were eligible for inclusion if they investigated insomnia at baseline (including nighttime- and daytime-symptoms) as a predictor of the later onset of psychopathology within a follow-up time-frame of at least 12 mo. Thirteen primary studies were included. The results suggest that insomnia is a significant predictor for the onset of depression (10 studies, OR 2.83, CI 1.55-5.17), anxiety (six studies, OR 3.23, CI 1.52-6.85), alcohol abuse (two studies, OR 1.35, CI 1.08-1.67, and psychosis (one study, OR 1.28, CI 1.03-1.59). The overall risk of bias in the primary studies was moderate. This meta-analysis provides evidence that insomnia increases the risk for psychopathology. A future research agenda should include more prospective studies using established diagnostic criteria, assessing insomnia at baseline and including long-term follow-up intervals evaluating a wider range of mental disorders. In addition, prospective long-term interventional studies investigating the efficacy of insomnia treatment for the prevention of mental disorders are called for.

Men in focus : Exploring homosocial cultures in organizations and developing methods to prevent sexual harassment
- 2021
-
Reports (other academic/artistic)abstract
- The program explores homosocial cultures in male-dominated organizations in order to contribute to our understanding of the dynamics of sexual harrassment and to develop measures and methods for transforming homosocial cultures into spaces where men in different positions can act as change agents in order to promote gender equality and workplaces free from violence and discrimination. This answers to recent calls for deepened understanding of processes by which sexual harassment is normalized and tolerated in organizational contexts and for improved prevention measures and methods (e.g. Chawla et al. 2021). By focusing on men and masculinities in relation to aspects of organizational cultures that enable men to exercise violence in order to maintain control in organizations, and by developing measures and methods for counteracting SH through organizational development, the program contributes to current research frontiers as well as to the development of new practices in organizational change management.

Smarta Loopar : En kartläggning av hinder och åtgärder för att ta fram smarta loopar för produkter av plast och textil, med fokus på policy och beteende
- 2021
-
Reports (other academic/artistic)abstract
- Ett vanligt argument för att inte sortera plastavfall utan i stället slänga det i brännbar avfallsfraktion är att volymerna av plastavfall är för små för att det skulle betala sig ekonomiskt att återvinna dem. Lösningen på detta har hittills varit att försöka samla in så mycket som möjligt för att sedan sortera i olika plastfraktioner. Med detta projekt har det utvärderat om man istället kan ha en specifik insamling och få mindre, men renare flöden, s.k. ”smarta loopar” av material.I projektet har det gjorts en kartläggning vad som skulle kunna fungera/ inte fungera och hitta möjligheter för att nå smarta loopar. Fokus i projektet låg på att identifiera hinder och åtgärder/lösningar som adresserar beteende och policyfrågor och inte på tekniska lösningar.Kartläggningen i projektet har genomförts med hjälp av fyra fallstudier: 1) Pallsträckfilm, 2) Spännband och lyftslingor, 3) plastemballage av kläder och 3) sportartiklar för innebandy. I projektet har det kartlagts båda på individuella hinder och åtgärder, som mer allmänna hinder och åtgärder som verkar vara gemensamt i de loopar projektet har tittat på.Projektet har visat att det redans finns bra exempel på fungerande smarta loopar i Sverige och det finns ett stort intresse hos svenskt näringsliv att ta fram flera smarta loopar. Det finns dock flera utmaningar kopplat till detta som diskuteras i projektet. Nu när flera hinder och potentiella åtgärder har kartlagts, krävs det att looparna testas och utvärderas i en liten skala. För företag som vill komma igång har projektet tagit fram en handlingsplan bestående av ett antal punkter man bör undersöka innan man startar.

Self-care of heart failure patients: practical management recommendations from the Heart Failure Association of the European Society of Cardiology
- 2021
-
In: European Journal of Heart Failure. - : WILEY. - 1388-9842 .- 1879-0844. ; 23:1, s. 157-174
-
Journal article (peer-reviewed)abstract
- Self-care is essential in the long-term management of chronic heart failure. Heart failure guidelines stress the importance of patient education on treatment adherence, lifestyle changes, symptom monitoring and adequate response to possible deterioration. Self-care is related to medical and person-centred outcomes in patients with heart failure such as better quality of life as well as lower mortality and readmission rates. Although guidelines give general direction for self-care advice, health care professionals working with patients with heart failure need more specific recommendations. The aim of the management recommendations in this paper is to provide practical advice for health professionals delivering care to patients with heart failure. Recommendations for nutrition, physical activity, medication adherence, psychological status, sleep, leisure and travel, smoking, immunization and preventing infections, symptom monitoring, and symptom management are consistent with information from guidelines, expert consensus documents, recent evidence and expert opinion.

Organisering av projektbaserade företag : Ledning, styrning och genomförande av projektbaserad industriell verksamhet
- 2009

Doctoral thesis (other academic/artistic)abstract
- This thesis focuses on the management and organizing of project-based companies, and the purpose is to enhance the understanding of multi-project management. The main part of the research and literature on project-based organizations has too narrow focus, since it is mainly interested in how to handle the difficulties that arise when executing a multi-project portfolio. Multi-project management is also often dominated by the thought of effectiveness and rationality through the use of project portfolio management methods and tools, which makes resource allocation and project priority the number one issue. Therefore, the profound theoretical ambition with this thesis is to complement the literature on project-based organizations with an empirically based understanding, inspired by organizing theory, for both research on, and practical execution of, multi-project management from a project-as-practice perspective. The thesis is based on case studies of two different project-based industrial companies, and the main methods for the empirical fieldwork were interviews and observations. The need for an organizing perspective on industrial organizations’ management and control of their project-based business originates from the importance of managing the need for organizational cooperation that arises because of the increased amount of temporary organizing procedures in a project-based company. This study sheds light on several important aspects for management and organizing of the special dynamics that characterize project-based organizations. One aspect is how the organizing of a project-based business demands a kind of insecurity-management, actions and activities aiming to balance the need for structure with the need for situated management. Another aspect is the importance of integrating the management and organizing of the multi-project business on a top management level.

D1.1. Integrated Framework. Deliverable to the MeBeSafe project
- 2018
-
Reports (other academic/artistic)abstract
- The MeBeSafe project intends to develop, implement and validate interventions that direct road users (drivers and cyclists) towards safer behaviour in common traffic situations which carry an elevated risk. More specifically, the aim is to change habitual traffic behaviour using different nudging interventions, i.e. subconsciously pushing road users in a desired direction without being prohibitive against alternative choices of action. The project will also compare different ways of coaching and evaluate the effect of a combination of nudging and coaching. This deliverable, D1.1 Integrated Framework, describes the work completed within WP1 of the MeBeSafe project. Based on literature reviews, interviews with academic and non-academic experts, discussions and workshops, the deliverable: (i) describes the key characteristics of nudging and coaching respectively; (ii) presents a framework that integrates the two, taking into consideration (in particular) time and frequency; (iii) describes underlying theories and models of relevance for understanding road user behaviour; (iii) explains road user profiles or characteristics of relevance to consider in the design of the interventions (i.e., in WP2, WP3, and WP4), as well as the design and interpretation of the outcome of the field trials (in WP5); and (iv) presents design considerations, i.e. factors that should be observed when improving on the initial ideas and further develop the design of the nudging and coaching interventions. More detailed design guidelines must be developed as part of the work to be completed in WP2, WP3, and WP4.

Journal article (peer-reviewed)abstract
- Recently, a locus on chromosome 6q22.33 (rs2180341) was reported to be associated with increased breast cancer risk in the Ashkenazi Jewish (AJ) population, and this association was also observed in populations of non-AJ European ancestry. In the present study, we performed a large replication analysis of rs2180341 using data from 31,428 invasive breast cancer cases and 34,700 controls collected from 25 studies in the Breast Cancer Association Consortium (BCAC). In addition, we evaluated whether rs2180341 modifies breast cancer risk in 3,361 BRCA1 and 2,020 BRCA2 carriers from 11 centers in the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA). Based on the BCAC data from women of European ancestry, we found evidence for a weak association with breast cancer risk for rs2180341 (per-allele odds ratio (OR) = 1.03, 95% CI 1.00-1.06, p = 0.023). There was evidence for heterogeneity in the ORs among studies (I(2) = 49.3%; p = <0.004). In CIMBA, we observed an inverse association with the minor allele of rs2180341 and breast cancer risk in BRCA1 mutation carriers (per-allele OR = 0.89, 95%CI 0.80-1.00, p = 0.048), indicating a potential protective effect of this allele. These data suggest that that 6q22.33 confers a weak effect on breast cancer risk.

Taktisk planering inom återvinningsbranschen – en fallstudie hos Ragn-Sells
- 2017
-
Conference paper (other academic/artistic)abstract
- Återvinningsindustrin samlar in och behandlaravfall som återvinns och säljs till kunder av återvunnen råvara. Att hålla ihopdessa aktiviteter är en utmanande uppgift bland annat på grund av hög variationkring kvantitet och kvalitet på det avfall som samlas in, osäkerheter kringefterfrågan av sekundär råvara, oklara prioriteringar kring tjänsten att samlain och behov att sälja produkter, samt en hög decentraliseringsgrad avverksamheten. För att erhålla ett högt resursutnyttjande och ta sundainvesterings-, sälj-, marknadsförings-, produktion- och logistikbeslut är detviktigt att skapa en samsyn kring vilken efterfrågan som finns på ett litelängre perspektiv och balansera denna mot tillgängliga resurser, vilket ärsyftet med taktisk planering. Det saknas dock kunskap och erfarenhet kringtaktisk planering i återvinningsindustrin. Syftet med studien är att fylla endel av detta kunskapsgap genom att ta fram en taktisk planeringsprocess med tillhörandeIT-verktyg för återvinningsföretaget Ragn-Sells. Studien har genomförts i närasamarbete mellan Ragn-Sells, systemutvecklaren Optimity och forskare inomlogistik och produktionsplanering. Planeringsprocessen utgörs av två parallellamånadsprocesser inom de två marknadsområden som är ansvariga för insamlingen avavfall, och koordineras vid ett gemensamt kvartalsmöte. En aktivitetsplaninnehållande vem som ska göra vad och när i processen samt mötesagendor hartagits fram. IT-verktyget stöttar i generering av en statistisk prognos ochframtagning av en nära optimal produktionsplan med avseende påkapacitetsutnyttjande och leveranssäkerhet. Planeringsprocessen ochIT-verktyget testades i form av ett rollspel där ett månadsmöte och ettkvartalsmöte iscensattes. En viktig slutsats från studien är attåtervinningsindustrins verksamhet befinner sig någonstans mellan ”projekt” och”tillverkning-mot-lager” och att det gäller att försöka minska osäkerheterkring den projektorienterade delen. Därför bör taktisk planering inomåtervinningsindustrin fokusera på att balansera nya anbud och utfasningar avkontrakt med tillgängliga resurser. I fortsatta studier är det intressant attinkludera övriga värdeadderande aktiviteter, förutom insamlingen, i planeringen.

Comparison of major depression diagnostic classification probability using the SCID, CIDI, and MINI diagnostic interviews among women in pregnancy or postpartum : An individual participant data meta-analysis
- 2019
-
In: International Journal of Methods in Psychiatric Research. - : WILEY. - 1049-8931 .- 1557-0657. ; 28:4
-
Journal article (peer-reviewed)abstract
- Objectives: A previous individual participant data meta-analysis (IPDMA) identified differences in major depression classification rates between different diagnostic interviews, controlling for depressive symptoms on the basis of the Patient Health Questionnaire-9. We aimed to determine whether similar results would be seen in a different population, using studies that administered the Edinburgh Postnatal Depression Scale (EPDS) in pregnancy or postpartum.Methods: Data accrued for an EPDS diagnostic accuracy IPDMA were analysed. Binomial generalised linear mixed models were fit to compare depression classification odds for the Mini International Neuropsychiatric Interview (MINI), Composite International Diagnostic Interview (CIDI), and Structured Clinical Interview for DSM (SCID), controlling for EPDS scores and participant characteristics.Results Among fully structured interviews, the MINI (15 studies, 2,532 participants, 342 major depression cases) classified depression more often than the CIDI (3 studies, 2,948 participants, 194 major depression cases; adjusted odds ratio [aOR] = 3.72, 95% confidence interval [CI] [1.21, 11.43]). Compared with the semistructured SCID (28 studies, 7,403 participants, 1,027 major depression cases), odds with the CIDI (interaction aOR = 0.88, 95% CI [0.85, 0.92]) and MINI (interaction aOR = 0.95, 95% CI [0.92, 0.99]) increased less as EPDS scores increased.Conclusion Different interviews may not classify major depression equivalently.

Tendinosis in Trigger Finger
- 2017
-
Doctoral thesis (other academic/artistic)abstract
- Trigger finger is one of the most common hand conditions, with a prevalence of almost 3%. The aetiology remains unclear even though many causes have been suggested. The prevailing paradigm is that the pathogenesis of trigger finger is ascribed to primary changes in the first fibrous condensation of the tendon sheath (A1-pulley). Several studies have investigated pathology in the pulley, but few have investigated the tendon. The general aim of this thesis was to find out if there is pathology in the trigger finger tendon and to define it.We first looked at trigger finger tendon biopsies in a light microscope, and found that they were histologically different from healthy tendons. They showed signs of micro-ruptures, collagen degradation, increased amounts of ground substance, both hyper- and hypo-cellular areas, round active cell nuclei and absence of inflammatory cells, all similar to tendinosis. The histological picture was further assessed by using a scoring system for Achilles tendinosis. The trigger finger tendons scored high, suggesting a similar histopathology.Next, we performed a quantitative real-time polymerase chain reaction (qPCR) on trigger finger tendons. We assessed the mRNA expression of 10 genes, which have been described to be differently expressed in Achilles tendinosis (collagen 1 and 3, versican, decorin, biglycan, aggrecan, MMP-2, MMP-3, ADAMTS-5, and TIMP-3). The overall expression pattern agreed with previous studies on Achilles tendinosis, suggesting that the cellular function in trigger finger tendons is disturbed in a similar way as in Achilles tendinosis.Recent experimental and observational research has suggested potential side effects of statin treatment on tendons, but firm evidence was lacking. We performed an epidemiological study on two large population-based cohorts. Statin use was found to increase the risk of both trigger finger and tendinosis in the shoulder and Achilles tendons, especially among men. This suggests a similar pathology in trigger finger and tendinosis.We have also studied the time to treatment effect after a single injection of glucocorticoid in trigger finger. Our results suggest that 60-80% of patients can expect resolution of the triggering within 14 days, and half of them within seven days. This result allows correct information to be given to the patient and proper planning of follow-ups.In conclusion, the pathology in trigger finger tendons is similar to tendinosis in other tendons.

Metabolic engineering of Thermoanaerobacterium AK17 for increased ethanol production in seaweed hydrolysate
- 2023
-
In: Biotechnology for Biofuels and Bioproducts. - 2731-3654. ; 16:1
-
Journal article (peer-reviewed)abstract
- Sustainably produced renewable biomass has the potential to replace fossil-based feedstocks, for generation of biobased fuels and chemicals of industrial interest, in biorefineries. In this context, seaweeds contain a large fraction of carbohydrates that are a promising source for enzymatic and/or microbial biorefinery conversions. The thermoanaerobe Thermoanaerobacterium AK17 is a versatile fermentative bacterium producing ethanol, acetate and lactate from various sugars. In this study, strain AK17 was engineered for more efficient production of ethanol by knocking out the lactate and acetate side-product pathways. This was successfully achieved, but the strain reverted to acetate production by recruiting enzymes from the butyrate pathway. Subsequently this pathway was knocked out and the resultant strain AK17_M6 could produce ethanol close to the maximum theoretical yield (90%), leading to a 1.5-fold increase in production compared to the wild-type strain. Strain AK17 was also shown to successfully ferment brown seaweed hydrolysate from Laminaria digitata to ethanol in a comparatively high yield of 0.45 g/g substrate, with the primary carbon sources for the fermentations being mannitol, laminarin-derived glucose and short laminari-oligosaccharides. As strain AK17 was successfully engineered and has a wide carbohydrate utilization range that includes mannitol from brown seaweed, as well as hexoses and pentoses found in both seaweeds and lignocellulose, the new strain AK17_M6 obtained in this study is an interesting candidate for production of ethanol from both second and third generations biomass.

Oxidative Cleavage of Cellobiose by Lytic Polysaccharide Monooxygenase (LPMO)-Inspired Copper Complexes
- 2019
-
In: ACS Omega. - : American Chemical Society (ACS). - 2470-1343. ; 4:6, s. 10729-10740
-
Journal article (peer-reviewed)abstract
- The potentially tridentate ligand bis[(1-methyl-2-benzimidazolyl)ethyl]amine (2BB) was employed to prepare copper complexes [(2BB)CuI]OTf and [(2BB)CuII(H2O)2](OTf)2 as bioinspired models of lytic polysaccharide copper-dependent monooxygenase (LPMO) enzymes. Solid-state characterization of [(2BB)CuI]OTf revealed a Cu(I) center with a T-shaped coordination environment and metric parameters in the range of those observed in reduced LPMOs. Solution characterization of [(2BB)CuII(H2O)2](OTf)2 indicates that [(2BB)CuII(H2O)2]2+ is the main species from pH 4 to 7.5; above pH 7.5, the hydroxo-bridged species [{(2BB)CuII(H2O)x}2(μ-OH)2]2+ is also present, on the basis of cyclic voltammetry and mass spectrometry. These observations imply that deprotonation of the central amine of Cu(II)-coordinated 2BB is precluded, and by extension, amine deprotonation in the histidine brace of LPMOs appears unlikely at neutral pH. The complexes [(2BB)CuI]OTf and [(2BB)CuII(H2O)2](OTf)2 act as precursors for the oxidative degradation of cellobiose as a cellulose model substrate. Spectroscopic and reactivity studies indicate that a dicopper(II) side-on peroxide complex generated from [(2BB)CuI]OTf/O2 or [(2BB)CuII(H2O)2](OTf)2/H2O2/NEt3 oxidizes cellobiose both in acetonitrile and aqueous phosphate buffer solutions, as evidenced from product analysis by high-performance liquid chromatography-mass spectrometry. The mixture of [(2BB)CuII(H2O)2](OTf)2/H2O2/NEt3 results in more extensive cellobiose degradation. Likewise, the use of both [(2BB)CuI]OTf and [(2BB)CuII(H2O)2](OTf)2 with KO2 afforded cellobiose oxidation products. In all cases, a common Cu(II) complex formulated as [(2BB)CuII(OH)(H2O)]+ was detected by mass spectrometry as the final form of the complex.

A cis-acting regulatory mutation causes premature hair graying and susceptibility to melanoma in the horse
- 2008
-
In: Nature Genetics. - : Springer Science and Business Media LLC. - 1061-4036 .- 1546-1718. ; 40:8, s. 1004-1009
-
Journal article (peer-reviewed)abstract
- In horses, graying with age is an autosomal dominant trait associated with a high incidence of melanoma and vitiligo-like depigmentation. Here we show that the Gray phenotype is caused by a 4.6-kb duplication in intron 6 of STX17 (syntaxin-17) that constitutes a cis-acting regulatory mutation. Both STX17 and the neighboring NR4A3 gene are overexpressed in melanomas from Gray horses. Gray horses carrying a loss-of-function mutation in ASIP (agouti signaling protein) had a higher incidence of melanoma, implying that increased melanocortin-1 receptor signaling promotes melanoma development in Gray horses. The Gray horse provides a notable example of how humans have cherry-picked mutations with favorable phenotypic effects in domestic animals.

Final Report of CBRNEmap : A better preparedness and response for European citizens facing CBRNE Threats
- 2011
-
Reports (pop. science, debate, etc.)abstract
- CBRNEmap was a pre-study to the upcoming CBRNE technology demonstrator. Accordingly, considerable efforts were used to describe the feasibility and to sort out a number of basic requirements of the contemplated demonstrator object. This report deals with two areas deemed important when constructing a civilian CBRNE system of systems, its limitations and some suggested specifications: A useful CBRNE system of systems will improve and connect important societal functions vital before, during and after a CBRNE accident and/or attack. CBRNEmap identifies three clusters of activities as the most important when making our society resilient to CBRNE. These are, the cluster of activities making up the response function, the cluster of activities defining the function to protect identified targets and the cluster of societal investments enabling Europe to become more resilient. As examples and as a source of inspiration the three societal functions described above (response, protect and enabling) were used to discuss the CBRNE technology demonstrator. The demonstrator objects were populated by technologies and thereafter discussed with respect to choice of scenarios, choice of parameters to be used for its validation and with respect to its market value. Based on its conclusions, its working process and its interaction with external partners CBRNEmap recommends that:The use of Integrated Project Teams will be given priority when evaluating the upcoming demonstrator objects.The European Commission does everything possible to ensure that the results of previous “EU project” get integrated into the upcoming demonstrator object.Appropriate limitations and projections are made to the CBRNE system of systems perspective, in order to produce a CBRNE demonstrator serving the societal functions responsible or operational active.Considerable efforts are given to validating the improvements and/or added value of the demonstrator object.The cluster of societal investment we refer to as the enabler is further investigated in a future SSA.

Establishment and characterization of a primary and a metastatic melanoma cell line from Grey horses
- 2014
-
In: In vitro Cellular & Developmental Biology-Animal. - : Springer Science and Business Media LLC. - 1071-2690 .- 1543-706X. ; 50:1, s. 56-65
-
Journal article (peer-reviewed)abstract
- The Grey horse phenotype, caused by a 4.6 kb duplication in Syntaxin 17, is strongly associated with high incidence of melanoma. In contrast to most human melanomas with an early onset of metastasis, the Grey horse melanomas have an extended period of benign growth, after which 50% or more eventually undergo progression and may metastasize. In efforts to define changes occurring during Grey horse melanoma progression, we established an in vitro model comprised of two cell lines, HoMel-L1 and HoMel-A1, representing a primary and a metastatic stage of the melanoma, respectively. The cell lines were examined for their growth and morphological characteristics, in vitro and in vivo oncogenic potential, chromosome numbers, and expression of melanocytic antigens and tumor suppressors. Both cell lines exhibited malignant characteristics; however, the metastatic HoMel-A1 showed a more aggressive phenotype characterized by higher proliferation rates, invasiveness, and a stronger tumorigenic potential both in vitro and in vivo. HoMel-A1 displayed a near-haploid karyotype, whereas HoMel-L1 was near-diploid. The cell lines expressed melanocytic lineage markers such as TYR, TRP1, MITF, PMEL, ASIP, MC1R, POMC, and KIT. The tumor suppressor p53 was strongly expressed in both cell lines, while the tumor suppressors p16 and PTEN were absent in HoMel-A1, potentially implicating significance of these pathways in the melanoma progression. This in vitro model system will not only aid in understanding of the Grey horse melanoma pathogenesis, but also in unraveling the steps during melanoma progression in general as well as being an invaluable tool for development of new therapeutic strategies.

Connecting Student Perceptions and Classroom Observations as Measures of Cognitive Activation
- 2022
-
In: Nordic Studies in Education. - : Cappelen Damm Akademisk. - 1891-5914 .- 1891-5949. ; 42:4, s. 328-346

Journal article (peer-reviewed)abstract
- Which dimensions of instruction can be reliably captured using student perception surveys, is subject for debate. The aim of this study is to empirically explore the validity and limitations of two different measures of cognitive activation: systematic classroom observations and student perceptions. 34 video-recorded lessons from ten lower secondary mathematics teachers in Iceland were analysed using an observation system and compared to 217 responses to the Tripod student perception survey. The results indicate that for the cognitive activation dimension, the connection between observer ratings and student perceptions is weak, raising questions about the validity of different measures of instructional quality.

Copy number expansion of the STX17 duplication in melanoma tissue from Grey horses
- 2012
-
In: BMC Genomics. - : Springer Science and Business Media LLC. - 1471-2164. ; 13, s. 365-
-
Journal article (peer-reviewed)abstract
- Background: Greying with age in horses is an autosomal dominant trait, associated with loss of hair pigmentation, melanoma and vitiligo-like depigmentation. We recently identified a 4.6 kb duplication in STX17 to be associated with the phenotype. The aims of this study were to investigate if the duplication in Grey horses shows copy number variation and to exclude that any other polymorphism is uniquely associated with the Grey mutation.Results: We found little evidence for copy number expansion of the duplicated sequence in blood DNA from Grey horses. In contrast, clear evidence for copy number expansions was indicated in five out of eight tested melanoma tissues or melanoma cell lines. A tendency of a higher copy number in aggressive tumours was also found. Massively parallel resequencing of the similar to 350 kb Grey haplotype did not reveal any additional mutations perfectly associated with the phenotype, confirming the duplication as the true causative mutation. We identified three SNP alleles that were present in a subset of Grey haplotypes within the 350 kb region that shows complete linkage disequilibrium with the causative mutation. Thus, these three nucleotide substitutions must have occurred subsequent to the duplication, consistent with our interpretation that the Grey mutation arose more than 2,000 years before present.Conclusions: These results suggest that the mutation acts as a melanoma-driving regulatory element. The elucidation of the mechanistic features of the duplication will be of considerable interest for the characterization of these horse melanomas as well as for the field of human melanoma research.

Imaging low-mass planets within the habitable zone of α Centauri
- 2021
-
In: Nature Communications. - : Springer Nature. - 2041-1723. ; 12:1
-
Journal article (peer-reviewed)abstract
- Giant exoplanets on wide orbits have been directly imaged around young stars. If the thermal background in the mid-infrared can be mitigated, then exoplanets with lower masses can also be imaged. Here we present a ground-based mid-infrared observing approach that enables imaging low-mass temperate exoplanets around nearby stars, and in particular within the closest stellar system, alpha Centauri. Based on 75-80% of the best quality images from 100h of cumulative observations, we demonstrate sensitivity to warm sub-Neptune-sized planets throughout much of the habitable zone of alpha Centauri A. This is an order of magnitude more sensitive than state-of-the-art exoplanet imaging mass detection limits. We also discuss a possible exoplanet or exozodiacal disk detection around alpha Centauri A. However, an instrumental artifact of unknown origin cannot be ruled out. These results demonstrate the feasibility of imaging rocky habitable-zone exoplanets with current and upcoming telescopes. Imaging of low-mass exoplanets can be achieved once the thermal background in the mid-infrared (MIR) wavelengths can be mitigated. Here, the authors present a ground-based MIR observing approach enabling imaging low-mass temperate exoplanets around nearby stars.
