Grov fridskränkning och grov kvinnofridskränkning : Fridskränkningsbrotten som rättslig konstruktion
- 2016

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Over the last decades men’s physical and psychological violence against women in intimate relationships (domestic violence) has become a central issue in Swedish politics. Men’s physical and psychological violence against women is generally be understood as including physical, sexual and psychological violence (e.g rape, battery, sexual abuse or insults) that occurs within the family, whether or not the perpetrator shares or has shared the same residence with the woman. Law reforms have been carried through with the objective of enhancing criminal legal protection for women. In 1999, a new law came into force within the framework of chapter 4 of the Penal Code which includes any member of the family with the objective to treat acts that are already criminal from a different perspective if they are committed within a pattern of systematic physical and psychological violence.This doctoral thesis examines the concept of domestic violence and the criminal act in Chapter 4, section 4 a of the Swedish Penal Code which prescribes liability for violation of integrity offences. According to the first paragraph, a person who commits criminal acts as defined in Chapters 3, 4, 6 or 12 or of the Swedish Penal Code (e.g. rape, battery, sexual abuse or insults) or violation of a restraining order against a person with whom they have or have previously had, a close relationship will be sentenced for gross violation of integrity to imprisonment for at least nine months and at most six years if each of the acts were part of a repeated violation of the person’s integrity and the acts were liable to severely damage the person’s self-esteem. The second paragraph states if the acts were committed by a man against a woman to whom he is, or has been married or with whom he is, or has been cohabiting under circumstances comparable to marriage. He will instead be sentenced for a gross violation of a woman’s integrity to the same punishment. The objective of introducing a violation of integrity offence was to enable criminal proceedings to take in to account the abused person’s entire situation when he or she has been subjected to a series of albeit punishable but often individually relatively minor acts and to bring about an upgrading of the penal value of such acts. The main purpose of this thesis is to examine when and under which circumstances a person can be held responsible for gross violation of integrity or gross violation of a woman’s integrity. The analysis aims at the construction of the law, but also to examine the legal and social consequences and the interpretation and application of the law.

Patients and Professionals as Partners in Hypertension Care: Qualitative Substudy of a Randomized Controlled Trial Using an Interactive Web-Based System Via Mobile Phone
- 2021

Tidskriftsartikel (refereegranskat)abstract
- Background: The use of technology has the potential to support the patient´s active participation regarding treatment of hypertension. This might lead to changes in the roles of the patient and health care professional and affect the partnership between them. Objective: The aim of this qualitative study was to explore the partnership between patients and health care professionals and the roles of patients and professionals in hypertension management when using an interactive web-based system for self-management of hypertension via the patient’s own mobile phone. Methods: Focus group interviews were conducted with 22 patients and 15 professionals participating in a randomized controlled trial in Sweden aimed at lowering blood pressure (BP) using an interactive web-based system via mobile phones. The interviews were audiorecorded and transcribed and analyzed using thematic analysis. Results: Three themes were identified: the technology, the patient, and the professional. The technology enabled documentation of BP treatment, mainly for sharing knowledge between the patient and the professional. The patients gained increased knowledge of BP values and their relation to daily activities and treatment. They were able to narrate about their BP treatment and take a greater responsibility, inspired by new insights and motivation for lifestyle changes. Based on the patient’s understanding of hypertension, professionals could use the system as an educational tool and some found new ways of communicating BP treatment with patients. Some reservations were raised about using the system, that it might be too time-consuming to function in clinical practice and that too much measuring could result in stress for the patient and an increased workload for the professionals. In addition, not all professionals and patients had adopted the instructions regarding the use of the system, resulting in less realization of its potential. Conclusions: The use of the system led to the patients taking on a more active role in their BP treatment, becoming more of an expert of their BP. When using the system as intended, the professionals experienced it as a useful resource for communication regarding BP and lifestyle. Patients and professionals described a consultation on more equal grounds. The use of technology in hypertension management can promote a constructive and person-centered partnership between patient and professional. However, implementation of a new way of working should bring benefits and not be considered a burden for the professionals. To establish a successful partnership, both the patient and the professional need to be motivated toward a new way of working.

- The Pregnancy Obesity Nutrition and Child Health study is a longitudinal study of reproductive health. Here we analyzed body composition of normal-weight and obese Swedish women by three methods during each trimester of pregnancy. Cross-sectional and longitudinal fat mass estimates using quantitative magnetic resonance (QMR) and bioelectrical impedance analysis (BIA) (Tanita MC-180MA-III) were compared with fat mass determined by air displacement plethysmography (ADP) in pregnancy weeks 8-12, 24-26, and 35-37 in normal-weight women (n = 122, BMI = 22.1 +/- 1.6 kg/m(2)) and obese women (n = 29, BMI = 34.6 +/- 3.6 kg/m(2)). ADP results were calculated from pregnancy-adjusted fat-free mass densities. Mean fat mass by QMR and ADP were similar in obese women, although with wide limits of agreement. In normal-weight women, QMR overestimated mean fat mass in all trimesters, with systematic overestimation at low fat mass values in trimesters 1 and 3. In obese women, fat mass by BIA was grossly underestimated and imprecise in all trimesters, especially at higher values in trimester 2. In normal-weight women, fat mass by BIA was moderately lower than by ADP in trimester 1, similar in trimester 2, and moderately higher in trimester 3. QMR and ADP assessed fat mass changes similarly in obese women, whereas BIA overestimated fat mass changes in normal-weight women. Mean fat mass and fat mass changes by QMR and pregnancy-adjusted ADP were similar in pregnant obese women. Mean fat mass by QMR and fat mass changes by BIA were higher than corresponding values determined by pregnancy-adjusted ADP in normal-weight women.

Identification of myocardial injury using perioperative troponin surveillance in major noncardiac surgery and net benefit over the Revised Cardiac Risk Index
- 2022
-
Ingår i: British Journal of Anaesthesia. - : Elsevier. - 0007-0912 .- 1471-6771. ; 128:1, s. 26-36

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Patients with perioperative myocardial injury are at risk of death and major adverse cardiovascular and cerebrovascular events (MACCE). The primary aim of this study was to determine optimal thresholds of preoperative and perioperative changes in high-sensitivity cardiac troponin T (hs-cTnT) to predict MACCE and mortality.METHODS: Prospective, observational, cohort study in patients ≥50 yr of age undergoing elective major noncardiac surgery at seven hospitals in Sweden. The exposures were hs-cTnT measured before and days 0-3 after surgery. Two previously published thresholds for myocardial injury and two thresholds identified using receiver operating characteristic analyses were evaluated using multivariable logistic regression models and externally validated. The weighted comparison net benefit method was applied to determine the additional value of hs-cTnT thresholds when compared with the Revised Cardiac Risk Index (RCRI). The primary outcome was a composite of 30-day all-cause mortality and MACCE.RESULTS: We included 1291 patients between April 2017 and December 2020. The primary outcome occurred in 124 patients (9.6%). Perioperative increase in hs-cTnT ≥14 ng L-1 above preoperative values provided statistically optimal model performance and was associated with the highest risk for the primary outcome (adjusted odds ratio 2.9, 95% confidence interval 1.8-4.7). Validation in an independent, external cohort confirmed these findings. A net benefit over RCRI was demonstrated across a range of clinical thresholds.CONCLUSIONS: Perioperative increases in hsTnT ≥14 ng L-1 above baseline values identifies acute perioperative myocardial injury and provides a net prognostic benefit when added to RCRI for the identification of patients at high risk of death and MACCE.CLINICAL TRIAL REGISTRATION: NCT03436238.

Genetic Studies of Pigmentation in Chicken
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Domestic animals have been selected by humans for thousands of years, which have drastically altered their genetic constitution and phenotypes. In this thesis, several of the most important genes causing pigmentation differences between the wild red junglefowl (Gallus gallus) and domestic chickens have been identified. Pigmentation phenotypes are easily scored, and the genes underlying these phenotypes are valuable models to study gene function and gene interaction. Dominant white colour is widespread among domestic chickens. The Dominant white allele specifically inhibits the expression of black (eumelanin) pigment and we identified several insertion/deletion mutations in the PMEL17 gene causing the different phenotypes controlled by this locus. The Silver allele on the other hand inhibits the expression of red (pheomelanin) colour and is a genetic variant of the SLC45A2 gene. Silver is the first pheomelanin-specific mutation(s) reported for this gene. An 8 kb deletion, including a conserved enhancer element, 14 kb upstream of the transcription factor SOX10 is causing the Dark brown phenotype. This phenotype restricts the expression of eumelanin and enhances red pheomelanin in specific parts of the plumage. These three gene identifications have extended the knowledge about genes affecting melanocyte function. Carotenoid-based pigmentation is of utmost importance in birds and other animals. The yellow skin allele in chicken allows deposition of carotenoids in skin and explains why most domestic chickens have yellow legs. We demonstrated that the yellow skin phenotype is caused by a tissue specific regulatory mutation in the gene for the enzyme beta-caroten dioxygenase 2 (BCDO2). This was the first identification of a specific gene underlying carotenoid-based pigmentation. Interestingly, the yellow skin haplotype was shown to originate from the grey junglefowl (Gallus sonneratii) and not the red junglefowl as expected, thus presenting the first conclusive evidence for a hybrid origin of the domestic chicken.

Tidskriftsartikel (refereegranskat)abstract
- ObjectiveDuring pregnancy, metabolic interactions must be adapted, though neuroendocrine mechanisms for increased food intake are poorly understood. The objective of this study was to characterize differences in insulin, leptin, and agouti-related protein (AgRP) levels in serum and cerebrospinal fluid (CSF) in pregnant women with normal weight (NW) and pregnant women with overweight (OW) or obesity (OB). Placenta as a source for increased peripheral AgRP levels during pregnancy was also investigated. MethodsWomen were recruited at admission for elective cesarean section. Insulin, AgRP, and leptin were measured in serum and CSF from 30 NW, 25 OW, and 21 OB at term. Serum during pregnancy and placenta at term were collected for further AgRP analysis. ResultsImmunohistology showed placental production of AgRP and serum AgRP levels increased throughout pregnancy. CSF AgRP, leptin, and insulin levels were higher in OW and OB than NW. Serum leptin and insulin levels were higher and AgRP lower in OB than NW. ConclusionsHigh serum AgRP levels might protect from the suppressive effects of leptin during pregnancy. Pregnant women with OB and OW might further be protected from the suppressive effect of leptin by high CSF AgRP levels. Evidence was found, for the first time, of human placental AgRP production mirrored by levels in the circulation.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: For primary health care (PHC), hypertension is the number one diagnosis for planned health care visits. The treatment of high blood pressure (BP) and its consequences constitutes a substantial economic burden. In spite of efficient antihypertensive medications, a low percentage of patients reach a well-controlled BP. The PERson-centredness in Hypertension management using Information Technology (PERHIT) Study is a multicentre randomised controlled trial. PERHIT is designed to evaluate the effect of supporting self-management on systolic blood pressure by the use of information technology in Swedish primary health care. Materials and Methods: After inclusion, 900 patients from 36 PHC centres are randomised to two groups. In the intervention group, patients are provided with a self-management support system including a home-BP monitor and further requested to perform self-reports and measure BP every evening for eight consecutive weeks. In the control group, patients receive treatment as usual. Results: The primary outcome will be the change in systolic blood pressure in patients with hypertension. In addition, person-centredness, daily life activities, awareness of risk and health care costs will also be evaluated. Conclusion: The results of this randomised controlled trial with assessment of blood pressure and same-day self-reports will provide patients a tool to understand the interplay between blood pressure and lifestyle applicable to primary health care. The self-management support system may be of importance for improved adherence to treatment and persistence to treatment recommendations.

- Background Olympic weightlifting and powerlifting are two sports that expose the body to great forces. Injury characteristics have not been systematically reviewed for these two growing sports.Objective The purpose of this study was to systematically review the literature regarding various definitions of injuries used, injury localisation, the prevalence and incidence of injuries and the associated risk factors for injuries in weightlifting and powerlifting.Design Systematic review.Data sources Five databases, PubMed, MEDLINE, SPORTDiscus, Scopus and Web of Science, were searched between 9 March and 6 April 2015.Eligibility criteria for selecting studies Studies assessing injury incidence and prevalence in Olympic weightlifting and powerlifting were included. The Quality assessment tool for observational cohort and cross-sectional studies was used to assess methodological quality.Results 9 studies were included in the review. Injury was defined fairly consistently across studies. Most studies were of low methodological quality. The spine, shoulder and the knee were the most common injury localisations in both sports. The injury incidence in weightlifting was 2.4–3.3 injuries/1000 hours of training and 1.0–4.4 injuries/1000 hours of training in powerlifting. Only one retrospective study had analysed possible risk factors.Summary/conclusions The risk of injury in both sports were similar to other non-contact sports also requiring strength/power, but low compared to contact sports. The severity of injuries differed in the included studies. Since little has been studied regarding possible risk factors to injuries, further research is therefore warranted to explain why athletes get injured and how to prevent injuries.Trial registration number PROSPERO CRD42015014805.

The Feeling of Migration : Narratives of Queer Intimacies and Partner Migration
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This dissertation analyzes narratives of queer partner migration, that is, a family-tie migration in which one of the partners of a relationship has migrated in order for the partners to be together, and where the partners queer the migration in the sense that they have a non-normative sexuality and/or gender identity. The purpose of the study is to examine how queer partner migrants and their Swedish partners experience the migration process – which continues also once the administrative process has been completed – by analyzing the emotions and feelings that emerge in the process. The study is a contribution to research on privileged migration as well as intimate migration.The focus is the queer partner migration relationship, and what emotions and feelings ‘do’ to this relationship, but also how emotions and feelings structure the migration process. The study analyzes the work three different emotions – love, loss, and belonging – do in these migration processes, and how this work is described in the participant narratives. Migrant participants have migrated from different parts of the world (Africa, Europe, Latin America, and North America), making it possible to analyze what emotions and feelings do in this particular migration process from the point of view of nationality and, in particular, proximity to ‘Western-ness,’ race, and language as well as how privileges connected to these positions come to matter in the process.The dissertation is an ethnographic interview study in which both migrants and Swedish partners have been interviewed. The interview material consists of a combination of couple interviews and individual interviews.By using affect theories and the concept of queer phenomenology, the dissertation shows how the work that emotions and feelings do in migration processes is connected to gender identity, sexual identity, race and whiteness, nationality, perceived proximity to Western-ness, class, language, and the migration narrative the migrating partner is (or is not) written into by way of the country they have migrated from. This is analyzed in relation to the theoretical frameworks of entanglement, homonationalism, and intimate citizenship.The analysis shows that emotions and feelings structure the migration process for both more privileged and less privileged migrants, but in different ways. The understanding of who ‘is’ a migrant, and the preparedness for the feelings that arise in a migration process, are tied to the positions mentioned above and the privileges these positions give, or do not give, the migrant access to. By focusing on emotions and feelings and what these do, the study also illustrates how the migration process affects the non-migrating partner as this partner engages in emotional labour to ‘make’ the migrating partner ‘Swedish.’ Through their the migrating partner, the non-migrating partner is also aligned in a way that makes them a little bit less ‘Swedish,’ contributing to the non-migrating partner being ‘stopped’ in ways they have usually not experienced before. The study further shows how migration processes produces inequality, and the difficulties that arise when the couples try to live up to the Swedish ideal of the equal relationship.The interviews are analyzed as narratives, and both narratives and storytelling are important throughout the dissertation, not only as the method used in the analysis but as the form of the dissertation, making it a kind of super structure organizing the writing. Writing (how to write accessibly and interesting) and reading (how to write in order to invite an open and active reading) are important aspects of the dissertation.

Antenatal care for Somali-born women in Sweden : Perspectives from mothers, fathers and midwives
- 2019
-
Ingår i: Midwifery. - : Elsevier BV. - 0266-6138 .- 1532-3099. ; 74, s. 107-115

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To explore Somali-born parents' experiences of antenatal care in Sweden, antenatal care midwives´ experiences of caring for Somali-born parents, and their respective ideas about group antenatal care for Somali-born parents.DESIGN: Eight focus group discussions with 2-8 participants in each were conducted, three with Somali-born mothers, two with fathers and three with antenatal care midwives. The transcribed text was analysed using Attride-Stirling´s tool "Thematic networks".SETTING: Two towns in mid-Sweden and a suburb of the capital city of Sweden.PARTICIPANTS: Mothers (n = 16), fathers (n = 13) and midwives (n = 7) were recruited using purposeful sampling.FINDINGS: Somali-born mothers and fathers in Sweden were content with many aspects of antenatal care, but they also faced barriers. Challenges in the midwife-parent encounter related to tailoring of care to individual needs, dealing with stereotypes, addressing varied levels of health literacy, overcoming communication barriers and enabling partner involvement. Health system challenges related to accessibility of care, limited resources, and the need for clear, but flexible routines and supportive structures for parent education. Midwives confirmed these challenges and tried to address them but sometimes lacked the support, resources and tools to do so. Mothers, fathers and midwives thought that language-supported group antenatal care might help to improve communication, provide mutual support and enable better dialogue, but they were concerned that group care should still allow privacy when needed and not stereotype families according to their country of birth.KEY CONCLUSIONS: ANC interventions targeting inequalities between migrants and non-migrants may benefit from embracing a person-centred approach, as a means to counteract stereotypes, misunderstandings and prejudice. Group antenatal care has the potential to provide a platform for person-centred care and has other potential benefits in providing high-quality antenatal care for sub-groups that tend to receive less or poor quality care. Further research on how to address stereotypes and implicit bias in maternity care in the Swedish context is needed.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: Comparing language-supported group antenatal care (gANC) and standard antenatal care (sANC) for Somali-born women in Sweden, measuring overall ratings of care and emotional well-being, and testing the feasibility of the outcome measures.Design: A quasi-experimental trial with one intervention and one historical control group, nested in an intervention development and feasibility study.Setting: Midwifery-led antenatal care clinic in a mid-sized Swedish town.Participants: Pregnant Somali-born women (<25 gestational weeks); 64women in gANC and 81 in sANC.Intervention: Language-supported gANC (2017-2019). Participants were offered seven 60-minute group sessions with other Somali-born women led by one to two midwives, in addition to 15-30min individual appointments with their designated midwife.Outcomes: Primary outcomes were women's overall ratings of antenatal care and emotional well-being (Edinburgh Postnatal Depression Scale (EPDS)) in gestational week >= 35and 2 months post partum. Secondary outcomes were specific care experiences, information received, social support, knowledge of pregnancy danger signs and obstetric outcomes.Results: Recruitment and retention of participants were challenging. Of eligible women, 39.3% (n=106) declined to participate. No relevant differences regarding overall ratings of antenatal care between the groups were detected (late pregnancy OR 1.42, 95% CI 0.50 to 4.16 and 6-8 weeks post partum OR 2.71, 95% CI 0.88 to 9.41). The reduction in mean EPDS score was greater in the intervention group when adjusting for differences at baseline (mean difference -1.89; 95% CI -3.73 to -0.07). Women in gANC were happier with received pregnancy and birth information, for example, caesarean section where 94.9% (n=37) believed the information was sufficient compared with 17.5% (n=7) in standard care (p<0.001) in late pregnancy.Conclusions: This evaluation suggests potential for language-supported gANC to improve knowledge acquisition among pregnant Somali-born women with residence in Sweden <10 years. An adequately powered randomised trial is needed to evaluate the effectiveness of the intervention.

Group antenatal care (gANC) for Somali-speaking women in Sweden - a process evaluation
- 2022
-
Ingår i: BMC Pregnancy and Childbirth. - : Springer Nature. - 1471-2393 .- 1471-2393. ; 22:1
-
Tidskriftsartikel (refereegranskat)abstract
- Background Language supported group antenatal care (gANC) for Somali-born women was implemented in a Swedish public ANC clinic. The women were offered seven 60-min sessions, facilitated by midwives and starting with a presentation of a selected topic, with an additional 15-min individual appointment before or after. The aim of this study was to assess the feasibility for participants and midwives of implementing The Hooyo ("mother" in Somali) gANC intervention, including implementation, mechanisms of impact and contextual factors. Methods A process evaluation was performed, using The Medical Research Council (MRC) guidelines for evaluating complex interventions as a framework. A range of qualitative and quantitative data sources were used including observations (n = 9), complementary, in-depth and key-informant interviews (women n = 6, midwives n = 4, interpreters and research assistants n = 3) and questionnaire data (women n = 44; midwives n = 8). Results Language-supported gANC offered more comprehensive ANC that seemed to correspond to existing needs of the participants and could address knowledge gaps related to pregnancy, birth and the Swedish health care system. The majority of women thought listening to other pregnant women was valuable (91%), felt comfortable in the group (98%) and supported by the other women (79%), and they said that gANC suited them (79%). The intervention seemed to enhance knowledge and cultural understanding among midwives, thus contributing to more women-centred care. The intervention was not successful at involving partners in ANC. Conclusions The Hooyo gANC intervention was acceptable to the Somali women and to midwives, but did not lead to greater participation by fathers-to-be. The main mechanisms of impact were more comprehensive ANC and enhanced mutual cultural understanding. The position of women was strengthened in the groups, and the way in which the midwives expanded their understanding of the participants and their narratives was promising. To be feasible at a large scale, gANC might require further adaptations and the "othering" of women in risk groups should be avoided.

- IMPORTANCE: In the Apixaban for Reduction of Stroke and Other Thromboembolic Complications in Atrial Fibrillation (ARISTOTLE) trial, the standard dose of apixaban was 5 mg twice daily; patients with at least 2 dose-reduction criteria-80 years or older, weight 60 kg or less, and creatinine level 1.5 mg/dL or higher-received a reduced dose of apixaban of 2.5 mg twice daily. Little is known about patients with 1 dose-reduction criterion who received the 5 mg twice daily dose of apixaban.OBJECTIVE: To determine the frequency of 1 dose-reduction criterion and whether the effects of the 5 mg twice daily dose of apixaban on stroke or systemic embolism and bleeding varied among patients with 1 or no dose-reduction criteria.DESIGN, SETTING, AND PARTICIPANTS: Among 18 201 patients in the ARISTOTLE trial, 17 322 were included in this analysis. Annualized event rates of stroke or systemic embolism and major bleeding and hazard ratios (HRs) and 95% CIs were evaluated. Interactions between the effects of apixaban vs warfarin and the presence of 1 or no dose-reduction criteria were assessed. The first patient was enrolled in the ARISTOTLE trial on December 19, 2006, and follow-up was completed on January 30, 2011. Data were analyzed from January 2015 to May 30, 2016.MAIN OUTCOMES AND MEASURES: Analysis of major bleeding included events during study drug treatment. Analysis of stroke or systemic embolism was based on intention to treat.RESULTS: Of the patients with 1 or no dose-reduction criteria assigned to receive the 5 mg twice daily dose of apixaban or warfarin, 3966 had 1 dose-reduction criterion; these patients had higher rates of stroke or systemic embolism (HR, 1.47; 95% CI, 1.20-1.81) and major bleeding (HR, 1.89; 95% CI, 1.62-2.20) compared with those with no dose-reduction criteria (n = 13 356). The benefit of the 5 mg twice daily dose of apixaban (n = 8665) compared with warfarin (n = 8657) on stroke or systemic embolism in patients with 1 dose-reduction criterion (HR, 0.94; 95% CI, 0.66-1.32) and no dose-reduction criterion (HR, 0.77; 95% CI, 0.62-0.97) were similar (P for interaction = .36). Similarly, the benefit of 5 mg twice daily dose of apixaban compared with warfarin on major bleeding in patients with 1 dose-reduction criterion (HR, 0.68; 95% CI, 0.53-0.87) and no dose-reduction criterion (HR, 0.72; 95% CI, 0.60-0.86) were similar (P for interaction = .71). Similar patterns were seen for each dose-reduction criterion and across the spectrum of age, body weight, creatinine level, and creatinine clearance.CONCLUSIONS AND RELEVANCE: Patients with atrial fibrillation and isolated advanced age, low body weight, or renal dysfunction have a higher risk of stroke or systemic embolism and major bleeding but show consistent benefits with the 5 mg twice daily dose of apixaban vs warfarin compared with patients without these characteristics. The 5 mg twice daily dose of apixaban is safe, efficacious, and appropriate for patients with only 1 dose-reduction criterion.TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00412984.

- Aim: To investigate the degree by which epigenetic signatures in children from mothers with gestational diabetes mellitus (GDM) are influenced by environmental factors. Methods: We profiled the DNA methylation signature of blood from lean, obese and GDM mothers and their respective newborns. Results: DNA methylation profiles of mothers showed high similarity across groups, while newborns from GDM mothers showed a marked distinct epigenetic profile compared with newborns of both lean and obese mothers. Analysis of variance in DNA methylation levels between newborns showed higher variance in the GDM group. Conclusion: Our results suggest that environmental factors, rather than direct transmission of epigenetic marks from the mother, are involved in establishing the epigenetic signature associated with GDM. © 2019 Romain Barrès.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: The incidence and progression of many autoimmune diseases are sex-biased, which might be explained by the immunomodulating properties of endocrine hormones. Treatment with estradiol potently inhibits experimental autoimmune arthritis. Interleukin-17-producing T helper cells (Th17) are key players in several autoimmune diseases, particularly in rheumatoid arthritis. The aim of this study was to investigate the effects of estrogen on Th17 cells in experimental arthritis. Methods: Ovariectomized DBA/1 mice treated with 17 beta-estradiol (E2) or placebo were subjected to collagen-induced arthritis (CIA), and arthritis development was assessed. Th17 cells in joints and lymph nodes were studied by flow cytometry. Lymph node Th17 cells were also examined in ovariectomized estrogen receptor a-knockout mice (ERa-/-) and wild-type littermates, treated with E2 or placebo and subjected to antigen-induced arthritis. Results: E2-treated mice with established CIA showed reduced severity of arthritis and fewer Th17 cells in joints compared with controls. Interestingly, E2-treated mice displayed increased Th17 cells in lymph nodes during the early phase of the disease, dependent on ER alpha. E2 increased the expression of C-C chemokine receptor 6 (CCR6) on lymph node Th17 cells as well as the expression of the corresponding C-C chemokine ligand 20 (CCL20) within lymph nodes. Conclusions: This is the first study in which the effects of E2 on Th17 cells have been characterized in experimental autoimmune arthritis. We report that E2 treatment results in an increase of Th17 cells in lymph nodes during the early phase of arthritis development, but leads to a decrease of Th17 in joints during established arthritis. Our data suggest that this may be caused by interference with the CCR6-CCL20 pathway, which is important for Th17 cell migration. This study contributes to the understanding of the role of estrogen in the development of autoimmune arthritis and opens up new fields for research concerning the sex bias in autoimmune disease.

- Interleukin-17 (IL-17) drives inflammation and destruction of joints in rheumatoid arthritis (RA). The female sex hormone 17β-estradiol (E2) inhibits experimental arthritis. γδT cells are significant producers of IL-17, thus the aim of this study was to investigate if E2 influenced IL-17(+) γδT cells during arthritis development using a variety of experimental RA models: collagen-induced arthritis (CIA); antigen-induced arthritis (AIA); and collagen antibody-induced arthritis (CAIA). We demonstrate that E2 treatment decreases IL-17(+) γδT cell number in joints, but increases IL-17(+) γδT cells in draining lymph nodes, suggesting an E2-mediated prevention of IL-17(+) γδT cell migration from lymph nodes to joints, in concert with our recently reported effects of E2 on Th17 cells (Andersson et al., 2015). E2 did neither influence the general γδT cell population nor IFNγ(+) γδT cells, implying a selective regulation of IL-17-producing cells. In conclusion, this study contributes to the understanding of estrogen's role in autoimmune disease.

Roles of activating functions 1 and 2 of estrogen receptor α in lymphopoiesis.

Tidskriftsartikel (refereegranskat)abstract
- Apart from the role of sex steroids in reproduction, sex steroids are also important regulators of the immune system. 17β-estradiol (E2) represses T and B cell development, but augments B cell function, possibly explaining the different nature of immune responses in men and women. Both E2 and selective estrogen receptors modulators (SERM) act via estrogen receptors (ER). Activating functions (AF)-1 and 2 of the ER bind to coregulators and thus influence target gene transcription and subsequent cellular response to ER activation. The importance of ERαAF-1 and AF-2 in the immunomodulatory effects of E2/SERM has previously not been reported. Thus, detailed studies of T and B lymphopoiesis were performed in ovariectomized E2-, lasofoxifene- or raloxifene-treated mice lacking either AF-1 or AF-2 domains of ERα, and their wild-type littermate controls. Immune cell phenotypes were analyzed with flow cytometry. All E2 and SERM-mediated inhibitory effects on thymus cellularity and thymic T cell development were clearly dependent on both ERαAFs. Interestingly, divergent roles of ERαAF-1 and ERαAF-2 in E2 and SERM-mediated modulation of bone marrow B lymphopoiesis were found. In contrast to E2, effects of lasofoxifene on early B cells did not require functional ERαAF-2, while ERαAF-1 was indispensable. Raloxifene reduced early B cells partly independent of both ERαAF-1 and ERαAF-2. Results from this study increase the understanding of the impact of ER modulation on the immune system, which can be useful in the clarification of the molecular actions of SERMs and in the development of new SERM.

- RA predominantly affects post-menopausal women and is strongly associated with development of generalised osteoporosis. To find treatments that target both joint manifestations and osteoporosis in RA is desirable. The third generation of selective oestrogen receptor modulators (SERMs) [lasofoxifene (LAS) and bazedoxifene (BZA)] are new treatment options for post-menopausal osteoporosis. The aim of this study was to investigate the effects of LAS and BZA on arthritic disease and inflammation-associated bone loss using CIA in mice.

- Public media both refects and shapes societal perceptions and attitudes. Teachers and others around students in mathematics classrooms have expectations for the students, projected with what appears in these media. We are most concerned about the expectationsplaced on students who are identifed with minoritized groups—particularly students whoare Indigenous or migrated to Norway. We investigate how minoritized group contexts andmathematics education appear together in Norwegian news media texts. Our analysis usesthe notion of storylines to describe the expectations about minoritized groups that newsmedia project. We found seven entangled storylines: “the majority language and cultureare keys to learning and knowing mathematics,” “mathematics is language- and cultureneutral,” “minoritized groups’ mathematics achievements are linked to culture and gender,”“extraordinary measures are needed to teach students from minoritized groups mathematics,” “students from minoritized groups underachieve,” “students from minoritized groupsput in extraordinary efort and time to learn mathematics,” and “minoritized mathematicsstudents are motivated by gratitude.”

- In addition to the systemic inflammation present in rheumatoid arthritis (RA), decreased estradiol levels in postmenopausal RA patients further accelerate bone loss in these patients. The tissue-selective estrogen complex (TSEC), an estrogen combined with a selective estrogen receptor modulator, is a new hormone replacement therapy option. The first approved TSEC, containing conjugated estrogens and bazedoxifene (BZA), reduces menopausal symptoms and prevents osteoporosis with an improved safety profile compared with conventional hormone replacement therapy. Previous studies have shown that estrogens strongly inhibit experimental arthritis whereas BZA is mildly suppressive. In this study the antiarthritic potential of combined BZA and estradiol is explored for the first time. Female ovariectomized DBA/1 mice were subjected to collagen-induced arthritis, an experimental postmenopausal RA model, and treated with BZA, 17β-estradiol (E2), combined BZA and E2 (BZA/E2), or vehicle. BZA/E2 suppressed arthritis severity and frequency, synovitis, and joint destruction, equally efficient as E2 alone. Unwanted estrogenic proliferative effects on the endometrium were blocked by the addition of BZA, determined by collecting uterine weights. Bone mineral density was measured by peripheral quantitative computed tomography, and all treatments protected collagen-induced arthritis mice from both trabecular and cortical bone loss. Moreover, BZA/E2, but not E2 alone, inhibited preosteoclast formation and reduced serum anticollagen type II antibodies. In conclusion, a TSEC, herein combined BZA/E2, suppresses experimental arthritis and prevents associated bone loss as efficiently as E2 alone but with minimal uterine effects, highlighting the need for clinical trials that evaluate the addition of a TSEC to conventional postmenopausal RA treatment.

Two shades of boldness : novel object and anti-predator behavior reflect different personality dimensions in domestic rabbits

Tidskriftsartikel (refereegranskat)abstract
- It is increasingly common to quantify and describe behavioral variation in domestic and wild animals in terms of personality. Correlating behavioral traits are referred to as personality dimensions or factors and different dimensions have been reported in different species. Boldness is a well-described personality dimension in several species, although some issues remain unclear. Previous models of boldness include both novelty and risk taking, but recent studies indicate that these types of behaviors may reflect separate personality dimensions. In this study, we developed a behavioral test battery for domestic rabbits, and recorded behaviors of 61 individuals in four different situations (novel object, novel arena, social, and predator interactions). We used domestic rabbits as a model because behavioral variation in rabbits has rarely been quantified in terms of personality dimensions, although rabbit behavior is described. We also wanted to investigate behavioral variation in a Swedish rabbit breed of conservation concern - the Gotland rabbit. Factor analysis of the behavioral test measures suggested three personality dimensions: exploration, boldness, and anxiety. Novel object scores clustered in the exploration and boldness factors, whereas scores associated with predator interactions were explained by anxiety, indicating that novel object and anti-predator behavior reflect different personality dimensions in rabbits.

Tidskriftsartikel (refereegranskat)abstract
- Succinic acid (SA) is an important platform molecule in the synthesis of a number of commodity and specialty chemicals. In the present work, dual-phase batch fermentations with the E. coli strain AFP184 were performed using a medium suited for large-scale industrial production of SA. The ability of the strain to ferment different sugars was investigated. The sugars studied were sucrose, glucose, fructose, xylose, and equal mixtures of glucose and fructose and glucose and xylose at a total initial sugar concentration of 100 g L-1. AFP184 was able to utilize all sugars and sugar combinations except sucrose for biomass generation and succinate production. For sucrose as a substrate no succinic acid was produced and none of the sucrose was metabolized. The succinic acid yield from glucose (0.83 g succinic acid per gram glucose consumed anaerobically) was higher than the yield from fructose (0.66 g g-1). When using xylose as a carbon source, a yield of 0.50 g g-1 was obtained. In the mixed-sugar fermentations no catabolite repression was detected. Mixtures of glucose and xylose resulted in higher yields (0.60 g g-1) than use of xylose alone. Fermenting glucose mixed with fructose gave a lower yield (0.58 g g-1) than fructose used as the sole carbon source. The reason is an increased pyruvate production. The pyruvate concentration decreased later in the fermentation. Final succinic acid concentrations were in the range of 25-40 g L-1. Acetic and pyruvic acid were the only other products detected and accumulated to concentrations of 2.7-6.7 and 0-2.7 g L-1. Production of succinic acid decreased when organic acid concentrations reached approximately 30 g L-1. This study demonstrates that E. coli strain AFP184 is able to produce succinic acid in a low cost medium from a variety of sugars with only small amounts of byproducts formed.

Effects of neutralising agent, organic acids, and osmolarity on succinic acid production by Escherichia coli AFP184
- 2008
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Using a low-cost medium Escherichia coli AFP184 has previously been reported to produce succinic acid with volumetric productivities close to 3 g L-1 h-1. At a total organic acid concentration of 30 g L-1 the productivity decreased drastically resulting in final succinate concentrations of 40 g L-1. The economical viability of biochemical succinic acid production would benefit from higher final succinic acid concentrations and volumetric productivities maintained at >2.5 g L-1 h-1 for an extended period of time. In the present work the effects of osmolarity and neutralising agent (NH4OH, KOH, NaOH, K2CO3, and Na2CO3) on succinic acid production by AFP184 were investigated. Highest concentration of succinic acid was obtained with Na2CO3, 75 g L-1. It was also found that the osmolarity resulting from succinate production and subsequent base addition, only marginally affected the productivity per viable cell. Organic acid inhibition due to the produced succinic acid on the other hand significantly reduced succinic acid productivity per viable cell. When using NH4OH productivity completely ceased at approximately 40 g L-1. Volumetric productivities remained at 2.5 g L-1 h-1 for 5 to 10 hours longer when using K- or Na-bases than when using NH4OH. However, loss of cell viability occurred, and together with the acid inhibition decreased the volumetric productivities. In this study it was demonstrated that by altering the neutralising agent it was possible to increase the period of high volumetric productivity in the anaerobic phase and improve the final succinic acid concentration by almost 100 %

Tidskriftsartikel (refereegranskat)abstract
- The economical viability of biochemical succinic acid production is a result of many processing parameters including final succinic acid concentration, recovery of succinate, and the volumetric productivity. Maintaining volumetric productivities >2.5 g L-1 h(-1) is important if production of succinic acid from. renewable resources should be competitive. In this work, the effects of organic acids, osmolarity, and neutralizing agent (NH4OH, KOH, NaOH, K2CO3, and Na2CO3) on the fermentative succinic acid production by Escherichia coli AFP184 were investigated. The highest concentration of succinic acid, 77 g L-1. was obtained with Na2O3. In general, irrespective of the base used, succinic acid productivity per viable cell was significantly reduced as the concentration of the produced acid increased. Increased osmolarity resulting from base addition during succinate production only marginally affected the productivity per viable cell. Addition of the osmoprotectant glycine betaine to cultures resulted in an increased aerobic growth rate and anaerobic glucose consumption rate, but decreased succinic acid yield. When using NH4OH productivity completely ceased at a succinic acid concentration of similar to 40 g L-1. Volumetric productivities remained at 2.5 g L-1 h(-1) for tip to 10 h longer when K- or Na-bases where used instead of NH4OH. The decrease in cellular succinic acid productivity observed during the anaerobic phase was found to be due to increased organic acid concentrations rather than medium osmolarity.

- During dual-phase fermentations using Escherichia coli engineered for succinic acid production, the productivity and viable cell concentration decrease as the concentration of succinic acid increases. The effects of succinic acid on the fermentation kinetics, yield, and cell viability were investigated by resuspending cells in fresh media after selected fermentation times. The cellular succinic acid productivity could be restored, but cell viability continuously decreased throughout the fermentations by up to 80% and subsequently the volumetric productivity was reduced. Omitting complex nutrients in the resuspension media had no significant effect on cellular succinate productivity and yield, although the viable cell concentration and thus the volumetric productivity was reduced by approximately 20%. By resuspending the cells, the amount of succinate produced during a 100-h fermentation was increased by more than 60%. The results demonstrate that by product removal succinic acid productivity can be maintained at high levels for extended periods of time.

Tidskriftsartikel (refereegranskat)abstract
- Ovarian carcinoma (OC) has a poor prognosis and lack early effective screening markers. Wilm's tumor gene 1 (WT1) is overexpressed in OCs. Therefore, it is of great interest to investigate whether WT1-specific antibody (Ab) measurements in plasma can serve as a biomarker of anti-OC response, and is of importance in relation to patient prognosis. Peripheral blood samples were obtained from a total of 103 women with ovarian tumors with median being 1 day (range 0-48 days) before operation. WT1 IgG Ab levels were evaluated using enzyme-linked immunosorbent assay (ELISA). Immunohistochemical analysis of WT1 protein expression was performed on OC tissue samples. We found that low-WT1 Ab level in plasma was related to improved survival in patients diagnosed at stages III-IV and grade 3 carcinomas. Positive WT1 protein staining on OC tissue samples had a negative impact on survival in the entire cohort, both overall survival (OS) (P = 0.046) and progression-free survival (PFS) (P = 0.006), but not in the serous OC subtype. Combining WT1 IgG Ab levels and WT1 staining, patients with high-WT1 IgG Ab levels in plasma and positive WT1 protein staining in cancer tissues had shorter survival, with a significant association in PFS (P = 0.016). These results indicated that WT1 Ab measurements in plasma and WT1 staining in tissue specimens could be useful as biomarkers for patient outcome in the high-risk subtypes of OCs for postoperative individualized therapy.

Plasticity Response in the Contralesional Hemisphere after Subtle Neurotrauma: Gene Expression Profiling after Partial Deafferentation of the Hippocampus
- 2013
-
Ingår i: Plos One. - : Public Library of Science (PLoS). - 1932-6203. ; 8:7
-
Tidskriftsartikel (refereegranskat)abstract
- Neurotrauma or focal brain ischemia are known to trigger molecular and structural responses in the uninjured hemisphere. These responses may have implications for tissue repair processes as well as for the recovery of function. To determine whether the plasticity response in the uninjured hemisphere occurs even after a subtle trauma, we subjected mice to a partial unilateral deafferentation of the hippocampus induced by stereotactically performed entorhinal cortex lesion (ECL). The expression of selected genes was assessed by quantitative real-time PCR in the hippocampal tissue at the injured side and the contralesional side at day 4 and 14 after injury. We observed that expression of genes coding for synaptotagmin 1, ezrin, thrombospondin 4, and C1q proteins, that have all been implicated in the synapse formation, re-arrangement and plasticity, were upregulated both in the injured and the contralesional hippocampus, implying a plasticity response in the uninjured hemisphere. Several of the genes, the expression of which was altered in response to ECL, are known to be expressed in astrocytes. To test whether astrocyte activation plays a role in the observed plasticity response to ECL, we took advantage of mice deficient in two intermediate filament (nanofilament) proteins glial fibrillary acidic protein (GFAP) and vimentin (GFAP(-/-) Vim(-/-)) and exhibiting attenuated astrocyte activation and reactive gliosis. The absence of GFAP and vimentin reduced the ECL-induced upregulation of thrombospondin 4, indicating that this response to ECL depends on astrocyte activation and reactive gliosis. We conclude that even a very limited focal neurotrauma triggers a distinct response at the contralesional side, which at least to some extent depends on astrocyte activation.

- Aim The aim of this study was to describe relatives' experiences of sharing a written life story about a close family member with dementia who has moved to residential care. Design An explorative descriptive qualitative design was used. Methods The data were collected using semi-structured interviews with a purposeful sample of eight relatives and analyzed using a qualitative content analysis. Results Results show that creating and sharing the life story of a close family member could help relatives handle grief and stress. It was perceived as an important, yet difficult, task to ensure that the close family member got good quality care. The creation of a meaningful life story takes time and requires cooperation with family members and other significant people.

Uppföljning av biologisk mångfald meddata från Riksskogstaxeringen : Slutrapport, mars 2012
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Denna rapport redovisar resultatet av ett samarbete mellan två projekt, dels ett projekt inom fortlöpandemiljöanalys på SLU, lett av Artdatabanken, dels ett projekt som letts av Länsstyrelsen i Jämtlandtillsammans med Artdatabanken och Skogsstyrelsen. Det senare drivs som ett så kallat miljömålsprojekt,med medel från Naturvårdsverket. I båda projekten är Riksskogstaxeringen en samarbetspartner.Grundtanken i båda projekten är att undersöka vilka parametrar i Riksinventeringen av skog (RIS) sombäst speglar tillståndet för biologisk mångfald.I ett första steg har arbetsgruppen valt ut ett antal parametrar som bör tas fram och undersökas. I ett andrasteg har SLU tagit fram ett bakgrundsmaterial som diskuterats vidare inom gruppen. Därefter har gruppentagit fram ett preliminärt förslag på vilka parametrar som kan vara lämpliga att prioritera för uppföljningav miljömålen. Förslaget har remitterats till forskare och myndigheter som kan tänkas ha intresse avinnehållet och inkomna synpunkter har inarbetats i föreliggande slutrapport. Innehållet kan utgöralämpligt bakgrundsmaterial om tillståndet i skogen, men också som indikatorer och andra mått som kananvändas på olika sätt i uppföljning av biologisk mångfald.Övergripande kan det konstateras att RIS ger värdefull kunskap om främst utvecklingen av skogligastrukturer som trädens ålder, trädslag, beståndsålder och andra kvaliteter. Denna information kan bidra tillatt beskriva förutsättningarna för den biologiska mångfalden. Ett flertal av parametrarna har haft enpositiv utveckling under miljömålsperioden. Det är däremot inte liktydigt med att utvecklingen för denbiologiska mångfalden utvecklats i en positiv riktning. Detta på grund av att de nivåer som vi har att utgåfrån (1999) ofta ligger på en så låg nivå jämfört med många arters behov att det krävs kraftigaförändringar för att arterna ska kunna utvecklas i positiv riktning.Projektet har hitintills prioriterat drygt ett tjugotal skogliga parametrar för uppföljning av biologiskmångfald inom miljömålssystemet. Av de skogliga parametrarna har följande föreslagits få hög prioritet:•Antal gamla träd över 121 år per kvadratkilometer, indelat i åldersklasser•Areal gammal skog fördelad på skogstyper; tall, gran, barr (ädel, barrädel, barrlöv)•Volym död ved av olika trädslag; tall, gran, löv•Volym död ved av olika grovlek•Areal ädellövskog indelad i åldersklasser•Areal ädellövskog fördelat på olika klasser för mängden död vedDe arter och spårtecken från inventeringen som särskilt uppmärksammats är:•Hackmärken•Vedsvamp•Tickor•Mjölkört•Hänglavar; man- och skägglav

- By combining the electrochromic (EC) properties of Prussian blue (PB) and poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS), complementary EC displays manufactured by slot-die coating and screen printing on flexible plastic substrates are reported. Various display designs have been realized, resulting in displays operating in either transmissive or reflective mode. For the transmission mode displays, the color contrast is enhanced by the complementary switching of the two EC electrodes PB and PEDOT:PSS. Both electrodes are either exhibiting a concurrent colorless or blue appearance. For the displays operating in reflection mode, a white opaque electrolyte is used in conjunction with the EC properties of PB, resulting in a display device switching between a fully white state and a blue-colored state. The developments of the different device architectures, that either operate in reflection or transmission mode, demonstrate a scalable manufacturing approach of all-printed EC displays that may be used in a large variety of Internet of Things applications. © 2022 The Authors.
