Tidskriftsartikel (refereegranskat)abstract
- Introduction: Post-stroke cognitive impairment (PSCI) is common, but evidence on the impact of vascular risk factors is lacking. We explored the association between pre-stroke vascular risk factors and PSCI and studied the course of PSCI.Materials and Methods: Vascular risk factors were collected at baseline in stroke survivors (n = 635). Cognitive assessments of attention, executive function, memory, language, and the Montreal Cognitive Assessment (MoCA) were performed at 3 and/or 18 months post-stroke. Stroke severity was assessed with the National Institutes of Health Stroke Scale (NIHSS). PSCI was measured with global z; MoCA z-score; and z-score of the four assessed cognitive domains. Mixed-effect linear regression was applied with global z, MoCA z-score, and z-scores of the cognitive domains as dependent variables. Independent variables were the vascular risk factors (hypertension, hypercholesterolemia, smoking, diabetes mellitus, atrial fibrillation, coronary heart disease, previous stroke), time, and the interaction between these. The analyses were adjusted for age, education, and sex. There were between 5 and 25% missing data for the variables for PSCI.Results: Mean age was 71.6 years (SD 11.7); 42% were females; and the mean NIHSS score at admittance was 3.8 (SD 4.8). Regardless of vascular risk factors, global z, MoCA, and all the assessed cognitive domains were impaired at 3 and 18 months, with MoCA being the most severely impaired. Atrial fibrillation (AF) was associated with poorer language at 18 months and coronary heart disease (CHD) with poorer MoCA at 18 months (LR =12.80, p = 0.002, and LR = 8.32, p = 0.004, respectively). Previous stroke was associated with poorer global z and attention at 3 and 18 months (LR = 15.46, p < 0.001, and LR = 16.20, p < 0.001). In patients without AF, attention improved from 3 to 18 months, and in patients without CHD, executive function improved from 3 to 18 months (LR = 10.42, p < 0.001, and LR = 9.33, p = 0.009, respectively).Discussion: Our findings indicate that a focal stroke lesion might be related to pathophysiological processes leading to global cognitive impairment. The poorer prognosis of PSCI in patients with vascular risk factors emphasizes the need for further research on complex vascular risk factor interventions to prevent PSCI.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study is to explore families' perceptions of everyday life when living with a young adult suffering from mental illness. Findings include: 1) Families balance between letting go and enabling the young adult to become independent while remaining close to help him/her complete education, work and have a social life. 2) Young adults try to deal with symptoms of mental illness by themselves and not be a burden, although longing for family members to understand them and the situation. 3) Healthcare professionals still hold back information although young adults have consented to giving family members insight.

Young Adults and Their Families Living With Mental Illness : Evaluation of the Usefulness of Family-Centered Support Conversations in Community Mental Health care Settings
- 2020

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to evaluate the usefulness of Family-Centered Support Conversations (FCSC) offered in community mental health care in Norway to young adults and their families experiencing mental illness. The FCSC is a family nursing intervention based on the Calgary Family Assessment and Intervention Models and the Illness Beliefs Model and is focused on how family members can be supportive to each other, how to identify strengths and resources of the family, and how to share and reflect on the experiences of everyday life together while living with mental illness. Interviews were conducted with young adults and their family members in Norway who had received the FCSC intervention and were analyzed using phenomenography. Two descriptive categories were identified: "Facilitating the sharing of reflections about everyday life" and "Possibility of change in everyday life." The family nursing conversations about family structure and function in the context of mental illness allowed families to find new meanings and possibilities in everyday life. Health care professionals can play an important role in facilitating a safe environment for young adults and their families to talk openly about the experience of living with and managing mental illness.

Air monitoring with passive samplers for dioxin-like persistent organic pollutants in developing countries (2017-2019)
- 2021
-
Ingår i: Chemosphere. - : Pergamon Press. - 0045-6535 .- 1879-1298. ; 287:Pt 1
-
Tidskriftsartikel (refereegranskat)abstract
- As part of the global monitoring plan on persistent organic pollutants (GMP) under the Stockholm Convention passive air samplers equipped with polyurethane foam disks (PUFs) were applied to monitor dioxin-like POPs. For sampling, toluene-pretreated PUFs were exposed for three months during two years. Chemical analysis was performed in one accredited expert laboratory using internationally accepted methods; for comparison, all results were normalized to one PUF and 3 month exposure. Total TEQs, using WHO2005-TEFs, were lowest in the Pacific Islands countries (PAC) and had similar mean values in Africa (16.8 pg TEQ/PUF), Asia (16.9 pg TEQ/PUF), and Latin American and Caribbean countries (GRULAC, 13.3 pg TEQ/PUF). Using median values, Asia (13.4 pg TEQ/PUF) and GRULAC (13.1 pg TEQ/PUF) had higher amounts than Africa (6.1 pg TEQ/PUF) and PAC (2.1 pg TEQ/PUF). The contribution of PCDD/PCDF to the total TEQ was 2-3-times higher than from the dl-PCB. Mono-ortho PCB did not play a role in any of the samples. The previous 40 samples during 2010/2011 and the present 195 samples from 2017/2018 did not show a statistical difference (p value = 0.3), only for GRULAC, a downward trend was identified. It is recommended combining 4 PUFs to ‘annual’ samples.

Fostering the truthful individual Communicating media literacy in the comic Bamse

Ingår i: Nordicom Review. - : Nordicom. - 1403-1108 .- 2001-5119. ; 42:1, s. 109-123

Tidskriftsartikel (refereegranskat)abstract
- This study examines the construction of media literacy in a special issue on source criticism of the Swedish children's comic Bamse - Varldens Starkaste Bjorn [Bamse - The World's Strongest Bear]. This is done with the purpose of understanding what values, perspectives, and practices are promoted when media literacy is communicated via children's edutainment media. Using narrative and discourse analysis, we problematise how notions of truth (such as post-truth) guide much of the discourse on digital media in today's post-political society, and how that and individualisation shape notions of media literacy. This is visible in the analysed case in how source criticism is constructed in relation to notions of truth and falsehood, and as moral lessons aimed at the individual media user. We argue that such an individualised, decontextualised, and depoliticised take on media literacy is problematic and an expression of neoliberalism and a middle-class gaze.

Do organizations really co-evolve? : Problematizing co-evolutionary change in management and organization studies
- 2020
-
Ingår i: Technological forecasting & social change. - : Elsevier. - 0040-1625 .- 1873-5509. ; 155
-
Tidskriftsartikel (refereegranskat)abstract
- This conceptual article discusses and, from some aspects, also problematizes the state-of-the-art regarding co-evolutionary research in Management and Organization Studies (MOS). Analyzing 76 characteristic studies published since 2000, we address three simple, significant questions: What co-evolves? What causal relationships are considered? What are the theoretical processes? The motivation behind our contribution is twofold: on the one hand, the turn of the century witnessed the remarkable growth of inquiries which, at face value, have claimed to be “co-evolutionary”; but, on the other hand, specific analyses about where this fast-growing meta-theoretical perspective on social change is now, and where it could move towards in the future, are still missing in MOS. Our study reveals increasing heterogeneity in defining what co-evolves and the associated causal relationships. It also reveals the prevailing scarcity in explaining what processes substantially characterize co-evolution in MOS. With a view to shaping the future direction of research in this area, we propose four core principles that theoretically set the co-evolutionary project apart.

Parental and trophic transfer of nanoscale plastic debris in an assembled aquatic food chain as a function of particle size
- 2021
-
Ingår i: Environmental Pollution. - : Springer. - 0269-7491 .- 1873-6424. ; 269
-
Tidskriftsartikel (refereegranskat)abstract
- The existing limitations in analytical techniques for characterization and quantification of nanoscale plastic debris (NPD) in organisms hinder understanding of the parental and trophic transfer of NPD in organisms. Herein, we used iron oxide-doped polystyrene (PS) NPD (Fe-PS-NPD) of 270 nm and Europium (Eu)-doped PS-NPD (Eu-PS-NPD) of 640 nm to circumvent these limitations and to evaluate the influence of particle size on the trophic transfer of NPD along an algae-daphnids food chain and on the reproduction of daphnids fed with NPD-exposed algae. We used Fe and Eu as proxies for the Fe-PS-NPD and Eu-Ps-NPD, respectively. The algae cells (Pseudokirchinella subcapitata) were exposed to 4.8 × 1010 particles/L of Fe-PS-NPD or Eu-PS-NPD for 72 h. A high percentage (>60%) of the NPD was associated with algal cells. Only a small fraction (<11%) of the NPD, however, was transferred to daphnids fed for 21 days on the NPD-exposed algae. The uptake and trophic transfer of the 270 nm Fe-PS-NPD were higher than those for the 640 nm Eu-PS-NPD, indicating that smaller NPD are more likely to transfer along food chains. After exposure to Fe-PS-NPD, the time to first brood was prolonged and the number of neonates per adult significantly decreased compared to the control without any exposure and compared to daphnids exposed to the Eu-Ps-NPD. The offspring of daphnids exposed to Eu-PS-NPD through algae, showed a traceable concentration of Eu, suggesting that NPD are transferred from parents to offspring. We conclude that NPD can be transferred in food chains and caused reproductive toxicity as a function of NPD size. Studies with prolonged exposure and weathered NPD are endeavored to increase environmental realism of the impacts determined.
