- Aim: The aim of this study was to explore healthcare professionals' experiences of working with extended home visits for parents. Background: It is essential to identify parents, both expectant and with a newborn child, who need support in their parenting abilities at an early stage because children's health and well-being are affected by their home environment as well as by their parents' health and social relationships. Home visits represent a cost-effective way of identifying and supporting families with a newborn. Further research is needed to explore healthcare professionals' experiences working with extended home visits for parents. Methods: This was a qualitative interview study focusing on an intervention introduced in the Enhanced Parenting - Extended Home Visits project in Sweden. Data were collected via 13 semi-structured interviews with healthcare professionals who provide the intervention in antenatal care (midwives) and child health care (CHC nurses and family supporters), and a qualitative content analysis was performed. Findings: Data analysis resulted in one theme and four categories. The theme - to provide multidimensional adapted professional support, - and the four categories - strengthened collaboration between professionals enriches their work. Home visits provide time for conversation, which promotes continuity of care and relationships with parents; being humble guests in parents' homes provides insight; and home visits provide the opportunity to strengthen parenting and participation in the family centre. The goals of the Enhanced Parenting - Extended Home Visits project were to strengthen parents' confidence in their parenting abilities and to build trusting relationships with healthcare professionals. The conclusion of this study, from the participants' perspective, is that these goals can be achieved with the intervention. Implications for Practice: Extended home visits seem to help healthcare professionals provide collaborative, multi-professional support for parents, both expectant and with a newborn child, with unique support needs.

- Objectives: Depression is increasing and is a leading cause of disease burden among adolescents. Available evidence-based treatments with medication or psychotherapy have modest effects. Aerobic exercise is a hopeful alternative as an augmenter or a stand-alone treatment. Qualitative studies have shown that participants in group exercise for adolescent depression experienced improved mood and a sense of achievement, commitment and empowerment. This study aimed to explore not only adolescents’ but also parents’ and healthcare professionals’ experiences of a group exercise intervention for adolescents with depression. Methods: Nine adolescents who had participated in a group aerobic exercise intervention for 12 weeks, eight parents and two healthcare professionals were interviewed. We used a latent qualitative content analysis with an inductive approach that resulted in nine sub-categories, three categories and an overarching theme. Results: The experiences of a group exercise intervention for adolescents with depression were expressed in the overarching theme ‘Group exercise for adolescent depression promotes empowerment and engagement in everyday life’, based on three categories: exercise alleviates depressive symptoms, exercise contributes to balance in life and exercise promotes self-esteem. However, there was variation in our results, in that not all participants experienced improvements from exercising. Adolescents described more varied experiences, while parents and healthcare professionals mainly expressed positive views. Conclusions: Our findings suggest that group exercise for adolescent depression promotes empowerment and engagement in everyday life, according to adolescents, and more clearly so according to parents and healthcare professionals. © The Author(s) 2024.

- INTRODUCTION: Depression is common, increasing among adolescents and carries risk of disability, lower educational achievements, cardiovascular disease, substance abuse, self-harm and suicide. The effects of evidence-based treatments with medication or psychotherapy are modest. Aerobic exercise is a promising intervention for adolescents with depression, but available studies are hampered by methodological shortcomings. This study aims to evaluate aerobic group exercise versus an active comparator of leisure group activities in adolescents from clinical services with mild-to-moderate depression.METHODS AND ANALYSIS: This study is a multicentre randomised controlled trial at four psychiatric clinics in Sweden. Participants (n=122) will be randomised 1:1 to group exercise delivered by exercise professionals and supported by mental health (MH) workers or leisure activities lead by the same MH workers for 1 hour three times a week for 12 weeks. Participants will be assessed at baseline, single blind after 13 weeks and 26 weeks and openly after 1 year. Participants randomised to the leisure group will be offered exercise in the open phase. The primary outcome is clinician-rated Children's Depression Rating Scale-Revised. Secondary outcomes are self-rated Quick Inventory of Depressive Symptomatology, self-rated functioning; clinician-rated improvement and functioning; objectively measured aerobic capacity, muscular strength, muscular endurance, body composition and presence or activity of selected biological markers of neuroprotection and neuroinflammation in blood samples. Further outcomes are cost-effectiveness and adolescents', parents' and coaches' experiences of the interventions and an exploration of how the adolescents' health and lifestyle are influenced by the interventions through qualitative interviews.ETHICS AND DISSEMINATION: The study is approved by the Swedish Ethical Review Authority (Ref. 2021-05307-01). Informed consent in writing will be provided from patients and parents of participants below 15 years of age. The results of this study will be communicated to the included participants and healthcare providers and also submitted for publication in peer-reviewed journals.TRIAL REGISTRATION NUMBER: NCT05076214.

- Introduction: Chronic lung disorders involve pathological alterations in the lung tissue with hypoxia as a consequence. Hypoxia may influence the release of inflammatory mediators and growth factors including vascular endothelial growth factor (VEGF) and prostaglandin (PG)E 2. The aim of this work was to investigate how hypoxia affects human lung epithelial cells in combination with profibrotic stimuli and its correlation to pathogenesis. Methods: Human bronchial (BEAS-2B) and alveolar (hAELVi) epithelial cells were exposed to either hypoxia (1% O 2) or normoxia (21% O 2) during 24 h, with or without transforming growth factor (TGF)-β1. mRNA expression of genes and proteins related to disease pathology were analysed with qPCR, ELISA or immunocytochemistry. Alterations in cell viability and metabolic activity were determined. Results: In BEAS-2B and hAELVi, hypoxia significantly dowregulated genes related to fibrosis, mitochondrial stress, oxidative stress, apoptosis and inflammation whereas VEGF receptor 2 increased. Hypoxia increased the expression of Tenascin-C, whereas both hypoxia and TGF-β1 stimuli increased the release of VEGF, IL-6, IL-8 and MCP-1 in BEAS-2B. In hAELVi, hypoxia reduced the release of fibroblast growth factor, epidermal growth factor, PGE 2, IL-6 and IL-8, whereas TGF-β1 stimulus significantly increased the release of PGE 2 and IL-6. TGF-β1 stimulated BEAS-2B cells showed a decreased release of VEGF-A and IL-8, while TGF-β1 stimulated hAELVi cells showed a decreased release of PGE 2 and IL-8 during hypoxia compared to normoxia. Metabolic activity was significantly increased by hypoxia in both epithelial cell types. Discussion: In conclusion, our data indicate that bronchial and alveolar epithelial cells respond differently to hypoxia and profibrotic stimuli. The bronchial epithelium appears more responsive to changes in oxygen levels and remodelling processes compared to the alveoli, suggesting that hypoxia may be a driver of pathogenesis in chronic lung disorders.

Konferensbidrag (refereegranskat)abstract
- The personal computer (PC) has been around for more than 35 years by now. Today, we find early adopters of the PC who have been using computers at home for 25 or 30 years and are now themselves in their eighties or nineties. Despite this there is still a lot of research focusing on how to introduce and teach the use of information technology to older people. In this paper we argue that it is time for a shift to designing for digital seniors, i.e., older long-time computer users. Over time this will be the dominating user group and we need to design for continued use of IT rather than guiding older computer novices. The paper also presents the concept Gracefully adaptive user interfaces and provides a case study in the form of a prototype re-design of Facebook aimed at exploring and illustrating how designing for digital seniors can be approached.

Pyrene Functionalized Norbornadiene-Quadricyclane Fluorescent Photoswitches: Characterization of their Spectral Properties and Application in Imaging of Amyloid Beta Plaques
- 2024

Tidskriftsartikel (refereegranskat)abstract
- This study presents the synthesis and characterization of two fluorescent norbornadiene (NBD) photoswitches, each incorporating two conjugated pyrene units. Expanding on the limited repertoire of reported photoswitchable fluorescent NBDs, we explore their properties with a focus on applications in bioimaging of amyloid beta (Aβ) plaques. While the fluorescence emission of the NBD decreases upon photoisomerization, aligning with what has been previously reported, for the first time we observed luminescence after irradiation of the quadricyclane (QC) isomer. We deduce how the observed emission is induced by photoisomerization to the excited state of the parent isomer (NBD) which is then the emitting species. Thorough characterizations including NMR, UV-Vis, fluorescence, X-ray structural analysis and density functional theory (DFT) calculations provide a comprehensive understanding of these systems. Notably, one NBD-QC system exhibits exceptional durability. Additionally, these molecules serve as effective fluorescent stains targeting Aβ plaques in situ, with observed NBD/QC switching within the plaques. Molecular docking simulations explore NBD interactions with amyloid, unveiling novel binding modes. These insights mark a crucial advancement in the comprehension and design of future photochromic NBDs for bioimaging applications and beyond, emphasizing their potential in studying and addressing protein aggregates.

- By-products from the food sector with a high load of organic matter present both a waste-handling problem related to expenses and to the environment, yet also an opportunity. This study aims to increase the value of stale bread and brewers spent grain (BSG) by re-introducing these residues to the food production chain by converting them to new protein-enriched products using the edible filamentous fungi Neurospora intermedia and Rhizopusoryzae. After 6 days of solid state fermentation (at 35°C, with a95% relative humidity and moisture content of 40% in the substrate) on stale bread, a nutrient-rich fungal-fermented product was produced. The total protein content, as analyzed by total amino acids, increased from 16.5% in stale sourdough bread to 21.1% (on dry weight basis) in the final product with an improved relative ratio of essential amino acids. An increase in dietary fiber, minerals (Cu, Fe, Zn) and vitamin E, as well as an addition of vitamin D2 (0.89 µg/g dry weight sample) was obtained compared with untreated stale bread. Furthermore, addition of BSG to the sourdough bread with the aim to improve textural changes after fermentation showed promising outcomes. Cultivation of N. intermedia or R. oryzae on stale sourdough bread mixed with 6.5% or 11.8% BSG, respectively, resulted in fungal-fermented products with similar textural properties to a commercial soybean burger. Bioconversion of stale bread and BSG by fungal solid state fermentation to produce a nutrient-enriched food product was confirmed to be a successful way to minimize food waste and protein shortage.

Assessment of corrosive attack of Fe9Cr1Mo alloys in pressurised CO2 for prediction of breakaway oxidation
- 2023
-
Ingår i: Corrosion Science. - : Elsevier BV. - 0010-938X .- 1879-0496. ; 222
-
Tidskriftsartikel (refereegranskat)abstract
- To provide clarity on the poorly-understood mechanism of breakaway oxidation, corrosion of Fe9Cr1Mo steel in pressurised CO2 is quantified and modelled. The temperature range 400-640 degrees C, relevant to nuclear power plants, is emphasised. Attack is in the form of combined oxide scale growth and internal carburisation of the metal. Carbon activity in the metal at its surface exhibits a strong time dependence consistent with the kinetically-limited transport of carbon due to the slow Boudouard reaction. Breakaway is associated with the approach to saturation of the steel with respect to carbon. Diffusion modelling agrees well with steel carbide precipitation observations.
