2.	Eriksson, Christina, et al. (författare) Occupational therapists' perceptions of implementing a client-centered intervention in close collaboration with researchers : A mixed methods study 2020 Ingår i: Scandinavian Journal of Occupational Therapy. - : Informa UK Limited. - 1103-8128 .- 1651-2014. ; 27:2, s. 142-153 Tidskriftsartikel (refereegranskat)abstract Background: Integration of research-based knowledge in health care is challenging. Occupational therapists (OTs) need to implement new research-based interventions in clinical practice. Therefore it is crucial to recognize and understand the factors of specific barriers and facilitators affecting the implementation process. Aim: To identify the key factors important for OTs during the implementation process of a complex intervention.Materials and methods: A cross-sectional study with a combination of qualitative and quantitative data in a mixed method design. Forty-one OTs and 23 managers from three county councils in Sweden, responded to a questionnaire one year after the OTs participation in a workshop to prepare for implementation of a client-centered activity of daily living intervention for persons with stroke.Results: Over 70% of the OTs benefitted from reading and discussing articles in the workshop; 60% had faith in the intervention; 69% reported usability of the intervention. High level of support from managers was reported, but less from team members. The therapists' interaction, perceptions of own efforts and contextual influence affected the implementation process.Conclusion: The workshop context with facilitation and access to evidence, supportive organizations and teams, sufficient interaction with researchers and satisfying self-image were successful key factors when involved in research.

4.	Abera, Asmamaw, et al. (författare) Air pollution measurements and land-use regression in urban sub-saharan Africa using low-cost sensors—possibilities and pitfalls 2020 Ingår i: Atmosphere. - : MDPI AG. - 2073-4433. ; 11:12 Tidskriftsartikel (refereegranskat)abstract Air pollution is recognized as the most important environmental factor that adversely affects human and societal wellbeing. Due to rapid urbanization, air pollution levels are increasing in the Sub-Saharan region, but there is a shortage of air pollution monitoring. Hence, exposure data to use as a base for exposure modelling and health effect assessments is also lacking. In this study, low-cost sensors were used to assess PM2.5 (particulate matter) levels in the city of Adama, Ethiopia. The measurements were conducted during two separate 1-week periods. The measurements were used to develop a land-use regression (LUR) model. The developed LUR model explained 33.4% of the variance in the concentrations of PM2.5. Two predictor variables were included in the final model, of which both were related to emissions from traffic sources. Some concern regarding influential observations remained in the final model. Long-term PM2.5 and wind direction data were obtained from the city’s meteorological station, which should be used to validate the representativeness of our sensor measurements. The PM2.5 long-term data were however not reliable. Means of obtaining good reference data combined with longer sensor measurements would be a good way forward to develop a stronger LUR model which, together with improved knowledge, can be applied towards improving the quality of health. A health impact assessment, based on the mean level of PM2.5 (23 µg/m3), presented the attributable burden of disease and showed the importance of addressing causes of these high ambient levels in the area.
5.	Assander, Susanne, et al. (författare) ASSIST : a reablement program for older adults in Sweden - a feasibility study 2022 Ingår i: BMC Geriatrics. - : Springer Nature. - 1471-2318. ; 22:1 Tidskriftsartikel (refereegranskat)abstract Background Western countries emphasise the provision of assistive home care by implementing reablement services. Reablement services are offered to a limited degree in Sweden, and systematic research regarding outcomes and how reablement can be tailored to maximize benefits for older adults has been lacking. This study aimed to evaluate the feasibility of a novel reablement program (ASSIST 1.0) regarding study design and outcome measures, as well as fidelity, adherence, and acceptability of the program in a Swedish context. Method A non-randomised, quasi-experimental, mixed-method, pre/post-test design was applied with an intervention group receiving ASSIST 1.0 (n = 7) and a control group receiving regular home care (n = 10). ASSIST 1.0 was developed to empower older adults to increase their perceived performance and satisfaction of performing activities in everyday life as well as increase their perceived health, self-efficacy, and well-being. ASSIST 1.0 was founded on the concept of reablement and included three components: i) goal setting with The Canadian Occupational Performance Measure (COPM), ii) provided support to home care staff to enhance their provision of reablement, and iii) explored the incorporation and use of an information- and communication technology (ICT) to facilitate information transfer. Results Using COPM for goal setting with older adults and providing support to the staff via workshops were valuable components in the delivery of ASSIST 1.0. The ICT product encountered several challenges and could not be evaluated. COPM and EQ-5D were deemed the most important instruments. Organisational and political barriers affected the feasibility. Although, the fidelity and adherence were complied the staff perceived the program to be acceptable. Conclusion The ASSIST 1.0 program was feasible in regard of study design, delivering the intervention, and evaluating instruments that detected a change. A logical progression would be to conduct a full-scale trial. In addition, a usability study to evaluate the technological component is also recommended. With minor improvements, the ASSIST 1.0 program has the potential to contribute to the development of a home care organisation that could enhance older adults possibility to age in place at home.
6.	Bark, Glenn, et al. (författare) Politikerna struntar i klimatforskningen : 420 forskare: Regeringens politik är katastrofal – nu måste fler svenskar kräva en omställning 2023 Ingår i: Aftonbladet Debatt. - 1103-9000. Tidskriftsartikel (populärvet., debatt m.m.)abstract DEBATE. We researchers have long demanded that the government take climate research seriously and speed up the transition to a sustainable society.Instead, the government is pursuing a policy that deliberately increases emissions. Now more citizens need to raise their voices and show that we demand a knowledge-based climate transition, and it is urgent.
7.	Bergemalm, Daniel, 1977-, et al. (författare) Systemic Inflammation in Preclinical Ulcerative Colitis 2021 Ingår i: Gastroenterology. - : AGA Institute. - 0016-5085 .- 1528-0012. ; 161:5, s. 1526-1539.e9 Tidskriftsartikel (refereegranskat)abstract Background & Aims: Preclinical ulcerative colitis is poorly defined. We aimed to characterize the preclinical systemic inflammation in ulcerative colitis, using a comprehensive set of proteins.Methods: We obtained plasma samples biobanked from individuals who developed ulcerative colitis later in life (n = 72) and matched healthy controls (n = 140) within a population-based screening cohort. We measured 92 proteins related to inflammation using a proximity extension assay. The biologic relevance of these findings was validated in an inception cohort of patients with ulcerative colitis (n = 101) and healthy controls (n = 50). To examine the influence of genetic and environmental factors on these markers, a cohort of healthy twin siblings of patients with ulcerative colitis (n = 41) and matched healthy controls (n = 37) were explored.Results: Six proteins (MMP10, CXCL9, CCL11, SLAMF1, CXCL11 and MCP-1) were up-regulated (P < .05) in preclinical ulcerative colitis compared with controls based on both univariate and multivariable models. Ingenuity Pathway Analyses identified several potential key regulators, including interleukin-1β, tumor necrosis factor, interferon-gamma, oncostatin M, nuclear factor-κB, interleukin-6, and interleukin-4. For validation, we built a multivariable model to predict disease in the inception cohort. The model discriminated treatment-naïve patients with ulcerative colitis from controls with leave-one-out cross-validation (area under the curve = 0.92). Consistently, MMP10, CXCL9, CXCL11, and MCP-1, but not CCL11 and SLAMF1, were significantly up-regulated among the healthy twin siblings, even though their relative abundances seemed higher in incident ulcerative colitis.Conclusions: A set of inflammatory proteins are up-regulated several years before a diagnosis of ulcerative colitis. These proteins were highly predictive of an ulcerative colitis diagnosis, and some seemed to be up-regulated already at exposure to genetic and environmental risk factors.
8.	Bergman, Fanny, et al. (författare) Physicochemical metamorphosis of re-aerosolized urban PM2.5 2024 Ingår i: Journal of Aerosol Science. - : Elsevier Ltd. - 0021-8502 .- 1879-1964. ; 181 Tidskriftsartikel (refereegranskat)abstract The toxicity of particulate matter (PM) is dependent on particle physical and chemical properties and is commonly studied using in vivo and in vitro approaches. PM to be used for in vivo and in vitro studies is often collected on filters and then extracted from the filter surface using a solvent. During extraction and further PM sample handling, particle properties change, but this is often neglected in toxicology studies, with possible implications for health effect assessment. To address the current lack of knowledge and investigate changes in particle properties further, ambient PM with diameter less than 2.5 μm (PM2.5) was collected on filters at an urban site and extracted using a standard methanol protocol. After extraction, the PM was dried, dispersed in water and subsequently nebulized. The resulting aerosol properties were then compared to those of the ambient PM2.5. The number size distribution for the nebulized aerosol resembled the ambient in terms of the main mode diameter, and >90 % of particle mass in the nebulized size distribution was still in the PM2.5 range. Black carbon made up a similar fraction of PM mass in nebulized as in ambient aerosol. The sulfate content in the nebulized aerosol seemed depleted and the chemical composition of the organic fraction was altered, but it remains unclear to what extent other non-refractory components were affected by the extraction process. Trace elements were not distributed equally across size fractions, neither in ambient nor nebulized PM. Change in chemical form was studied for zinc, copper and iron. The form did not appear to be different between the ambient and nebulized PM for iron and copper, but seemed altered for zinc. Although many of the studied properties were reasonably well preserved, it is clear that the PM2.5 collection and re-aerosolization process affects particles, and thus potentially also their health effects. Because of this, the effect of the particle collection and extraction process must be considered when evaluating cellular and physiological outcomes upon PM2.5 exposure. © 2024 The Authors

(författare) Pharmacological targeting of MTHFD2 suppresses acute myeloid leukemia by inducing thymidine depletion and replication stress 2022 Ingår i: NATURE CANCER. - : Springer Science and Business Media LLC. - 2662-1347. ; 3:2, s. 156- Tidskriftsartikel (refereegranskat)abstract The folate metabolism enzyme MTHFD2 (methylenetetrahydrofolate dehydrogenase/cyclohydrolase) is consistently overexpressed in cancer but its roles are not fully characterized, and current candidate inhibitors have limited potency for clinical development. In the present study, we demonstrate a role for MTHFD2 in DNA replication and genomic stability in cancer cells, and perform a drug screen to identify potent and selective nanomolar MTHFD2 inhibitors; protein cocrystal structures demonstrated binding to the active site of MTHFD2 and target engagement. MTHFD2 inhibitors reduced replication fork speed and induced replication stress followed by S-phase arrest and apoptosis of acute myeloid leukemia cells in vitro and in vivo, with a therapeutic window spanning four orders of magnitude compared with nontumorigenic cells. Mechanistically, MTHFD2 inhibitors prevented thymidine production leading to misincorporation of uracil into DNA and replication stress. Overall, these results demonstrate a functional link between MTHFD2-dependent cancer metabolism and replication stress that can be exploited therapeutically with this new class of inhibitors. Helleday and colleagues describe a nanomolar MTHFD2 inhibitor that causes replication stress and DNA damage accumulation in cancer cells via thymidine depletion, demonstrating a potential therapeutic strategy in AML tumors in vivo.

12.	Cediel Ulloa, Andrea, et al. (författare) Toxicity of stainless and mild steel particles generated from gas-metal arc welding in primary human small airway epithelial cells 2021 Ingår i: Scientific Reports. - : Springer Nature. - 2045-2322. ; 11:1 Tidskriftsartikel (refereegranskat)abstract Welding fumes induce lung toxicity and are carcinogenic to humans but the molecular mechanisms have yet to be clarified. The aim of this study was to evaluate the toxicity of stainless and mild steel particles generated via gas-metal arc welding using primary human small airway epithelial cells (hSAEC) and ToxTracker reporter murine stem cells, which track activation of six cancer-related pathways. Metal content (Fe, Mn, Ni, Cr) of the particles was relatively homogenous across particle size. The particles were not cytotoxic in reporter stem cells but stainless steel particles activated the Nrf2-dependent oxidative stress pathway. In hSAEC, both particle types induced time- and dose-dependent cytotoxicity, and stainless steel particles also increased generation of reactive oxygen species. The cellular metal content was higher for hSAEC compared to the reporter stem cells exposed to the same nominal dose. This was, in part, related to differences in particle agglomeration/sedimentation in the different cell media. Overall, our study showed differences in cytotoxicity and activation of cancer-related pathways between stainless and mild steel welding particles. Moreover, our data emphasizes the need for careful assessment of the cellular dose when comparing studies using different in vitro models.
13.	Davidsson, Sabina, 1972-, et al. (författare) Androgen deprivation therapy in men with prostate cancer is not associated with COVID-2019 infection 2023 Ingår i: The Prostate. - : Alan R. Liss Inc.. - 0270-4137 .- 1097-0045. ; 83:6, s. 555-562 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Androgens may play a role in severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection and host responses as the virus is dependent on the androgen-regulated protein transmembrane serine protease 2 for cell entry. Studies have indicated that prostate cancer patients receiving androgen deprivation therapy (ADT) are at reduced risk of SARS-CoV-2 infection and serious complications compared with patients without ADT, but data are inconsistent.METHODS: A total of 655 prostate cancer patients who were under surveillance at two urology departments in Sweden on April 1, 2020 were included in the study as well as 240 patients with benign prostatic hyperplasia (BPH). At follow-up early in 2021, the participants completed a questionnaire containing information about symptoms compatible with coronavirus disease 2019 (COVID-19). Blood samples were also collected for the assessment of SARS-CoV-2 IgG antibodies (SARS-CoV-2 Total; Siemens). We used multivariable logistic regression models to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for the association between ADT and the risk of SARS-CoV-2 infection.RESULTS: The cumulative incidence of SARS-CoV-2 seropositivity was 13.4% among patients receiving ADT and 10.4% among patients without ADT. After adjusting for potential confounders, we observed no differences in symptoms or risk of SARS-CoV-2 infection between patients with and without ADT (OR: 0.98; 95% CI: 0.52-1.85). Higher body mass index, Type 1 diabetes, and prostate cancer severity, defined by high Gleason score (8-10; OR: 2.06; 95% CI: 1.04-4.09) or elevated levels of prostate-specific antigen (>20 µg/l; OR: 2.15; 95% CI: 1.13-4.07) were associated with increased risk of SARS-CoV-2 infection. Overall, the risk of SARS-CoV-2 infection was not higher among men with prostate cancer than among men with BPH.CONCLUSIONS: Our results do not support the hypothesis that ADT use in prostate cancer patients reduces the risk or symptom severity of SARS-CoV-2 infection or that prostate cancer patients are at increased risk of COVID-19 compared with men without prostate cancer.

(författare) Men with impaired glucose tolerance have lower self-rated health than men with impaired fasting glucose 2020 Ingår i: Primary Care Diabetes. - : Elsevier BV. - 1751-9918. ; 14:1, s. 40-46 Tidskriftsartikel (refereegranskat)abstract Aim: Previous studies have shown that individuals with impaired glucose tolerance (IGT) have lower self-rated health than normoglycaemic individuals. The aim of this study was to examine differences in self-rated health between individuals with IGT and those with impaired fasting glucose (IFG) and to consider the potentially mediating effect of physical activity. Methods: In 2002–2005, a total of 2816 individuals were randomly selected for a population-based study in Sweden. All participants performed an oral glucose tolerance test (OGTT). Fasting venous blood samples were drawn, and questionnaires concerning lifestyles were completed. Self-rated health (SRH) and leisure time physical activity (LTPA) were reported on a five-graded and four-graded scale, respectively. A total of 213 individuals with IGT and 129 with IFG were detected. Results: IGT, but not IFG, was associated with low self-rated health. The difference in self-rated health was seen particularly in men when adjusted for age and BMI (OR = 2.13, CI: 1.13–4.02, p = 0.020). The results became insignificant when including physical activity in the model (OR = 1.8, CI: 0.91–3.58, p = 0.094). Conclusion: The low self-rated health adds further weight to the risk profile in men with IGT and stresses the importance of early detection and lifestyle interventions. © 2019

16.	Edvardsson, Anneli, et al. (författare) Robustness and dosimetric verification of hippocampal-sparing craniospinal pencil beam scanning proton plans for pediatric medulloblastoma 2024 Ingår i: Physics and Imaging in Radiation Oncology. - : Elsevier. - 2405-6316. ; 29 Tidskriftsartikel (refereegranskat)abstract Background and PurposeHippocampal-sparing (HS) is a method that can potentially reduce late cognitive complications for pediatric medulloblastoma (MB) patients treated with craniospinal proton therapy (PT). The aim of this study was to investigate robustness and dosimetric plan verification of pencil beam scanning HS PT.Materials and MethodsHS and non-HS PT plans for the whole brain part of craniospinal treatment were created for 15 pediatric MB patients. A robust evaluation of the plans was performed. Plans were recalculated in a water phantom and measured field-by-field using an ion chamber detector at depths corresponding to the central part of hippocampi. All HS and non-HS fields were measured with the standard resolution of the detector and in addition 16 HS fields were measured with high resolution. Measured and planned dose distributions were compared using gamma evaluation.ResultsThe median mean hippocampus dose was reduced from 22.9 Gy (RBE) to 8.9 Gy (RBE), while keeping CTV V95% above 95 % for all nominal HS plans. HS plans were relatively robust regarding hippocampus mean dose, however, less robust regarding target coverage and maximum dose compared to non-HS plans. For standard resolution measurements, median pass rates were 99.7 % for HS and 99.5 % for non-HS plans (p < 0.001). For high-resolution measurements, median pass rates were 100 % in the hippocampus region and 98.2 % in the surrounding region.ConclusionsA substantial reduction of dose in the hippocampus region appeared feasible. Dosimetric accuracy of HS plans was comparable to non-HS plans and agreed well with planned dose distribution in the hippocampus region.

(författare) Does persistent (patent) foramen ovale closure reduce the risk of recurrent decompression sickness in scuba divers? 2021 Ingår i: Diving and hyperbaric medicine. - : Diving and Hyperbaric Medicine Journal. - 1833-3516 .- 2209-1491. ; 51:1, s. 63-67 Tidskriftsartikel (refereegranskat)abstract Introduction: Interatrial communication is associated with an increased risk of decompression sickness (DCS) in scuba diving. It has been proposed that there would be a decreased risk of DCS after closure of the interatrial communication, i.e., persistent (patent) foramen ovale (PFO). However, the clinical evidence supporting this is limited. Methods: Medical records were reviewed to identify Swedish scuba divers with a history of DCS and catheter closure of an interatrial communication. Thereafter, phone interviews were conducted with questions regarding diving and DCS. All Swedish divers who had had catheter-based PFO-closure because of DCS were followed up, assessing post-closure diving habits and recurrent DCS. Results: Nine divers, all with a PFO, were included. Eight were diving post-closure. These divers had performed 6,835 dives (median 410, range 140-2,200) before closure, and 4,708 dives (median 413, range 11-2,000) after closure. Seven cases with mild and 10 with serious DCS symptoms were reported before the PFO closure. One diver with a small residual shunt suffered serious DCS post-closure; however, that dive was performed with a provocative diving profile. Conclusion: Divers with PFO and DCS continue to dive after PFO closure and this seems to be fairly safe. Our study suggests a conservative diving profile when there is a residual shunt after PFO closure, to prevent recurrent DCS events.

(författare) Effectiveness of a 3-Month Mobile Phone-Based Behavior Change Program on Active Transportation and Physical Activity in Adults : Randomized Controlled Trial. 2020 Ingår i: JMIR mhealth and uhealth. - : JMIR Publications. - 2291-5222. ; 8:6, s. 1-15 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Active transportation (AT; ie, walking and cycling as a mode for transportation) has been associated with decreased morbidity and mortality; however, low-cost and scalable intervention programs are lacking.OBJECTIVE: The goal of the research was to determine the effectiveness of a 3-month behavior change program delivered via a mobile phone app to promote AT (TravelVu Plus) on time spent in moderate-to-vigorous physical activity (MVPA).METHODS: For this 2-arm parallel randomized controlled trial, we recruited a population-based sample of 254 adults from Stockholm County who were aged 20 to 65 years and had access to a smartphone. On completion of 1-week baseline measures, the 254 participants were randomized to either the control or intervention group (1:1 ratio). Both groups had access to the standard TravelVu app (Trivector AB) for monitoring their AT for 6 months. The intervention group also received a 3-month behavior change program to promote AT (TravelVu Plus app). Assessors of outcomes were blinded to group allocation. Outcomes were objectively measured MVPA at 3 (primary) and 6 months. Secondary outcomes were AT, attitudes toward AT, and health-related quality of life at 3 and 6 months.RESULTS: No effect on MVPA was observed after 3 months (P=.29); however, at 6 months the intervention group had a greater improvement in MVPA than the controls (6.05 minutes per day [95% CI 0.36 to 11.74; P=.04]). A Bayesian analyses showed that there was a 98% probability that the intervention had any effect at 6 months, and a 63% probability that this effect was >5 minute MVPA per day.CONCLUSIONS: No effect on MVPA immediately after the intervention period (at 3 months) was observed; however, there was a delayed effect on MVPA (6 minutes per day) at 6 months, which corresponds to approximately 30% of the weekly MVPA recommendation. Our findings suggest that a behavior change program promoting AT delivered via an app may have a relevant effect on PA.TRIAL REGISTRATION: ClinicalTrials.gov NCT03086837; https://clinicaltrials.gov/ct2/show/NCT03086837.INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): RR2-10.1186/s12889-018-5658-4.
19.	Engberg, Adam, et al. (författare) An open source extrusion bioprinter based on the E3D motion system and tool changer to enable FRESH and multimaterial bioprinting 2021 Ingår i: Scientific Reports. - : Springer Nature. - 2045-2322. ; 11:1 Tidskriftsartikel (refereegranskat)abstract Bioprinting is increasingly used to create complex tissue constructs for an array of research applications, and there are also increasing efforts to print tissues for transplantation. Bioprinting may also prove valuable in the context of drug screening for personalized medicine for treatment of diseases such as cancer. However, the rapidly expanding bioprinting research field is currently limited by access to bioprinters. To increase the availability of bioprinting technologies we present here an open source extrusion bioprinter based on the E3D motion system and tool changer to enable high-resolution multimaterial bioprinting. As proof of concept, the bioprinter is used to create collagen constructs using freeform reversible embedding of suspended hydrogels (FRESH) methodology, as well as multimaterial constructs composed of distinct sections of laminin and collagen. Data is presented demonstrating that the bioprinted constructs support growth of cells either seeded onto printed constructs or included in the bioink prior to bioprinting. This open source bioprinter is easily adapted for different bioprinting applications, and additional tools can be incorporated to increase the capabilities of the system.
20.	Eriksson, Axel Christian, et al. (författare) Influence of airborne particles' chemical composition on SVOC uptake from PVC flooring - time resolved analysis with aerosol mass spectrometry 2020 Ingår i: Environmental Science & Technology. - : American Chemical Society (ACS). - 1520-5851 .- 0013-936X. ; , s. 85-91 Tidskriftsartikel (refereegranskat)abstract We sampled ammonium sulfate particles and indoor particles of outdoor origin through a small chamber covered with polyvinyl chloride (PVC) flooring. We measured the uptake of semi-volatile organic compounds (SVOC) by the airborne particles in real time. The particles acquired SVOC mass fractions up to 10%. The phthalate ester DEHP (di(2-ethylhexyl)phthalate), a known endocrine disruptor, contributed by approximately half of the sorbed SVOC mass. The indoor particles acquired higher DEHP fraction than laboratory generated ammonium sulfate aerosol. We attribute this increased uptake to absorption by organic matter present in the indoor particles. Using a thermodenuder to remove volatile components, predominantly organics, reduced SVOC uptake. Positive matrix factorization applied to the organic mass spectra suggests that hydrocarbon-like organic aerosol (typically fresh traffic exhaust) sorbs DEHP more efficiently than aged organic aerosol. SVOC uptake is one of the processes that modifies outdoor pollution particles after they penetrate buildings, where the majority of exposure occurs. Particles from indoor sources, typically dominated by organic matter, will undergo such processes as well. Aerosol mass spectrometry improves the time resolution of experimental investigations into these processes, and enables experiments with lower, relevant particle concentrations. Additionally, particle size resolved results are readily obtained.

22.	Eriksson, Axel, et al. (författare) Characterization of fine particulate matter from indoor cooking with solid biomass fuels 2022 Ingår i: Indoor Air. - : Hindawi Limited. - 0905-6947 .- 1600-0668. ; 32:11 Tidskriftsartikel (refereegranskat)abstract Household burning of solid biomass fuels emits pollution particles that are a huge health risk factor, especially in low-income countries (LICs) such as those in Sub-Saharan Africa. In epidemiological studies, indoor exposure is often more challenging to assess than outdoor exposure. Laboratory studies of solid biomass fuels, performed under real-life conditions, are an important path toward improved exposure assessments. Using on- and offline measurement techniques, particulate matter (PM) from the most commonly used solid biomass fuels (charcoal, wood, dung, and crops residue) was characterized in laboratory settings using a way of burning the fuels and an air exchange rate that is representative of real-world settings in low-income countries. All the fuels generated emissions that resulted in concentrations which by far exceed both the annual and the 24-hour-average WHO guidelines for healthy air. Fuels with lower energy density, such as dung, emitted orders of magnitude more than, for example, charcoal. The vast majority of the emitted particles were smaller than 300 nm, indicating high deposition in the alveoli tract. The chemical composition of the indoor pollution changes over time, with organic particle emissions often peaking early in the stove operation. The chemical composition of the emitted PM is different for different biomass fuels, which is important to consider both in toxicological studies and in source apportionment efforts. For example, dung and wood yield higher organic aerosol emissions, and for dung, nitrogen content in the organic PM fraction is higher than for the other fuels. We show that aerosol mass spectrometry can be used to differentiate stove-related emissions from fuel, accelerant, and incense. We argue that further emission studies, targeting, for example, vehicles relevant for LICs and trash burning, coupled with field observations of chemical composition, would advance our understanding of air pollution in LIC. We believe this to be a necessary step for improved air quality policy.

(författare) Sustainable Writing Support: A Campus-wide Module to Support Bachelor Thesis Writing at a University of Technology 2021 Ingår i: Educare - vetenskapliga skrifter. - : Malmo University Library. - 1653-1868. ; :1, s. 9-26 Tidskriftsartikel (refereegranskat)abstract Higher education is today characterised by increasing student groups and high pressure on teaching staff. In these circumstances, it may be difficult to provide appropriate scaffolding of activities that many students find challenging, for example, academic and discipline-specific writing. It may also be difficult to align such support with principles associated with effective learning. In this paper, we present the design of the bachelor thesis writing support for students at a university of technology. The support is delivered by a communication division and reaches approximately 900 students each year. The paper describes the principles guiding the design and use results from a student survey to illuminate the challenges and affordances of the approach. The survey results show that students appreciate the module and its focus on dialogic feedback, student engagement and student activity. Our results also show that one of the challenges for some students is to negotiate advice from multiple sources, primarily content supervisors and writing staff. Despite such challenges, the design is an example of a sustainable, large-scale writing module based on research on feedback and learning.

(författare) A climate report gone missing : power mechanisms in Swedish national transport planning 2024 Ingår i: European Planning Studies. - : Routledge. - 0965-4313 .- 1469-5944. Tidskriftsartikel (refereegranskat)abstract While the technological development of vehicles and fuels is not adequate to meet current climate mitigation targets, infrastructure development also plays an important role in transforming the transport system. Previous studies have argued that conventional infrastructure planning is incapable of implementing climate mitigation. The aim of the paper is to provide insights into power means and mechanisms that counteract integration of climate mitigation targets in infrastructure planning. This is done by an in-depth case study of current Swedish national transport planning. This case provides a rich illustration of a situation with high political ambitions regarding climate mitigation on the one hand, and power mechanisms and resistance with regard to climate goals during the planning process on the other. The case is analysed using the perspective of power circuits and shows how forecasting works as an obligatory passage point, sorting in and out which analyses will be part of the decision-making material. Analyses which do not fit the forecasting model are dismissed from planning. The conclusion is that as long as the transport infrastructure planning practice is dependent on forecasting as the only central analysis there will be difficulties in changing the scope of infrastructure planning and making climate goals central for transport planning.
25.	Eriksson, Maria Christina, 1981 (författare) Health locus of control, depressive symptoms, and insulin resistance. Implications for treatment and prevention in general population and primary care 2022 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract The disease burden of type 2 diabetes and depression is large and challenging for healthcare systems. Preventive interventions require resources and better knowledge concerning early stages in the development of these diseases. The aims of this thesis were to explore psychological distress (PD), internal health locus of control (IHLC) and insulin resistance in the population and to investigate the effectiveness of internet-based cognitive behavioural therapy (ICBT) for depression in primary care. Moreover, we aimed to investigate the validity of the question used for IHLC. The association between PD, IHLC and insulin resistance was analyzed in a random population sample (n=2816) in southwest Sweden, the Vara-Skövde Cohort (participation rate: 76%). Papers II and III evaluate ICBT for depression compared with treatment as usual (TAU) in primary care, at post-treatment (II), and after one year (III) in an randomized controlled trial called PRIM-NET (n=90). A validation of IHLC against the Multidimensional Health Locus of Control and the General Self-Efficacy Scale was carried out in Paper IV (n=519). Individuals with low IHLC had higher insulin resistance compared with those with high IHLC, and individuals with PD had higher insulin resistance compared with those without PD. However, the statistically significant differences disappeared in the full models. Individuals with both low IHLC and PD had higher levels of logHOMA-ir also in the final model adjusting for age, sex, education, smoking, alcohol consumption, BMI, and physical activity (Mean difference: 0.11, 95% CI:0.00-0.09, p=0.033). ICBT for depression was equally effective as TAU in primary care. There were no differences between ICBT and TAU in depressive symptoms, psychological distress, quality of life or sick leave. Weak, but positive support was found for using the global scale IHLC to measure IHLC. In conclusion, ICBT can be delivered as a routine treatment alternative in primary care and may improve preventive interventions in primary care on a larger scale. Individuals with PD and low IHLC seem to be at higher risk of developing insulin resistance, and preventive interventions in this group may prevent or delay development of type 2 diabetes.

(författare) Validation of a single question to measure internal health locus of control in Swedish primary care 2023 Ingår i: Scandinavian Journal of Psychology. - 0036-5564 .- 1467-9450. ; 64:5, s. 674-678 Tidskriftsartikel (refereegranskat)abstract BackgroundBehavioral risk factors are highlighted in the prevention of diabetes and cardiovascular disease. Screening for health locus of control could be a feasible way to better identify individuals who could benefit from preventive behavioral change interventions. The aim of the study was to investigate the correlation between a single question measuring internal health locus of control (IHLC) and the Multidimensional Health Locus of Control Scale (MHLC) and to assess how IHLC relates to the General Self-Efficacy scale (GSE) in a primary care setting. MethodsPrimary care patients, aged 18 and older, attending three primary care centers in southwest Sweden were consecutively asked to anonymously participate in the study. The patients were given a questionnaire and instructed to return the questionnaire in a sealed box in the waiting room. ResultsIn all, 519 patients were included. The correlation between MHLC Internality and IHLC was weak (r = 0.21, p < 0.001). An increase of one point on the internality scale of the MHLC gave an odds ratio of 1.19 (95% CI 1.11-1.28) for reporting high IHLC, and thus a five-point increase gave a doubled likelihood, OR = 2.40, CI 1.67-3.46. The results for the other scales of the MHLC and GSE were similar. ConclusionIn this study, we found weak but statistically significant support for the single-question IHLC as a measure of internal health locus of control. Given that the correlation was weak, we recommend using the MHLC when possible.

Untreated significant CoA has a major impact on morbidity and mortality. In the past 3 decades, transcatheter intervention (TCI) for CoA has evolved as an alternative to surgery.OBJECTIVES The authors report on all TCIs for CoA performed from 2000 to 2016 in 4 countries covering 25 million inhabitants, with a mean follow-up duration of 6.9 years.METHODS During the study period, 683 interventions were performed on 542 patients.RESULTS The procedural success rate was 88%, with 9% considered partly successful. Complications at the intervention site occurred in 3.5% of interventions and at the access site in 3.5%. There was no in-hospital mortality. During follow-up, TCI for CoA reduced the presence of hypertension significantly from 73% to 34%, but despite this, many patients remained hypertensive and in need of continuous antihypertensive treatment. Moreover, 8% to 9% of patients needed aortic and/or aortic valve surgery during follow-up.CONCLUSIONS TCI for CoA can be performed with a low risk for complications. Lifetime follow-up after TCI for CoA seems warranted. (J Am Coll Cardiol Intv 2023;16:444-453) & COPY; 2023 by the American College of Cardiology Foundation.
28.	Fichtel, Joakim (författare) Interorganizational Networks, Financing and Commercialization of Life Science Innovations 2024 Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract The biotechnology industry is known for being highly networked and knowledge-intensive, as well as highly internationalized. Young firms within this sector are reliant on long term support from financiers, research collaborators and supply of highly skilled human capital. Further, contributing to the unique circumstances for entrepreneurship in this industry, it is not uncommon for firms to have no product or service, nor revenues, many years or even decades after its founding. Creating and maintaining relationships with their external environment therefore becomes essential for survival.This thesis aims to study how interorganizational networks form over time and to contribute to the understanding of how activities of entrepreneurial actors draw on and shape the networks in which they are embedded. To achieve this, 319 Swedish firms in the Swedish biotechnology industry were studied longitudinally over a period of ten years. Data was collected on their activities and relationships with actors in the entrepreneurial ecosystem surrounding biotechnology firms. A relational database of 7,745 interactions between 2,868 unique actors was constructed and analyzed using social network analysis, and additional statistical analysis was performed using panel data linear regression modeling.The findings suggest that there are significant differences in how structural characteristics of the different layers within interorganizational networks enable and constrain entrepreneurial firms in their relationships with external stakeholders. The entrepreneurial ecosystems are presented as supra-local phenomena, integrated in and through networks transcending traditional geographical confines of ecosystems. The result of this thesis underscores the importance of understanding the multi-layered and international dimensions of interorganizational networks, particularly in a knowledge-intensive and globally interconnected industry like biotechnology. An important outcome of this research is that it underscores the importance of financing for bringing biotechnology innovations to market.

(författare) Air Pollution and Urban Green Space : Evidence of Environmental Injustice in Adama, Ethiopia 2021 Ingår i: Frontiers in Sustainable Cities. - : Frontiers Media SA. - 2624-9634. ; 3 Tidskriftsartikel (refereegranskat)abstract While air pollution data in Ethiopia is limited, existing studies indicate high levels of both ambient and household air pollution; rapid urbanization also threatens the preservation of urban green spaces. In this study, environmental injustice, or the disproportionate burden of environmental exposures on persons of lower socioeconomic status (SES), was explored among women in Ethiopia using a mother and child cohort from the city of Adama. Land-use regression models were previously developed for modeling ambient nitrogen dioxide (NO2) and nitrogen oxides (NOx) throughout Adama, while household air pollution (cooking fuel type) and the presence of green space were assessed through questionnaires and home visits, respectively. The odds of being exposed to these environmental factors were analyzed in association with two SES indicators, education and occupation, using logistic regression. Our results indicate the presence of environmental injustice in Adama, as women with lower SES shouldered a higher burden of air pollution exposure and enjoyed less urban green space than their higher SES counterparts. These findings encourage the prioritization of air quality control and urban planning resources toward policy action within lower SES areas. From a societal perspective, our results also support more upstream interventions, including investment in educational and occupational opportunities. Still, a human rights approach is emphasized, as governments are responsible for protecting the right to a clean environment, especially for those disproportionately exposed. To the best of our knowledge, this is the first study on environmental injustice in Ethiopia, and the first in Sub-Saharan Africa to investigate the inequalities of ambient and household air pollution exposure as well as urban green space access in the same cohort.

We investigated cardiovascular and bleeding risk in patients with atrial fibrillation with varying BMI.Methods and Results: Observational cohort study from the Swedish oral anticoagulation registry between August 2, 2011, and December 31, 2018. Primary outcomes were mortality, ischemic stroke/systemic embolism, and major bleeding. Baseline BMI (kg/m(2)) was analyzed continuously and categorized: underweight (<18.5 kg/m(2)), normal weight (18.5 to <25 kg/m(2)), preobesity (25 to <30 kg/m(2)), and obesity class I to III (30 to <35, 35 to <40, and >= 40 kg/m(2)). Adjusted Cox models and nonlinear relationships of BMI were modeled using restricted cubic splines. Non-vitamin K oral anticoagulant-treated patients with atrial fibrillation were included (n=26 047). At baseline, 602 (2.3%) were underweight, 9101 (34.9%) were normal weight, 9970 (38.3%) were preobese, 4280 (16.4%) were obese class I, 1486 (5.7%) were obese class II, and 608 (2.3%) were obese class III. Underweight and obesity class III were in adjusted continuous analysis associated with increased mortality and major bleeding, with lowest risk observed among preobese patients with BMI 28.2 and 26.2 kg/m(2), respectively. In adjusted categorical analysis, underweight was associated with increased mortality (hazard ratio [HR], 1.77 [95% CI, 1.57-1.99]) and nonsignificant higher risk of major bleeding (HR, 1.23 [95% CI, 0.95-1.58]). Similarly, obesity class III was associated with increased mortality (HR, 1.67 [95% CI, 1.40-1.99]) and major bleeding (HR, 1.68 [95% CI, 1.29-2.17]). No significant association was observed between higher BMI and ischemic stroke/systemic embolism.Conclusions: In non-vitamin K oral anticoagulant-treated patients with atrial fibrillation, there appears to be a U-shaped relationship between BMI and mortality and major bleeding.

Equipercentile linking analysis of PHQ-9 and EQ-5D 2021 Ingår i: Evidence-Based Mental Health. - : BMJ. - 1362-0347 .- 1468-960X. ; 24:3, s. 97-101 Tidskriftsartikel (refereegranskat)abstract Background: Quality-adjusted life years (QALYs) are widely used to measure the impact of various diseases on both the quality and quantity of life and in their economic valuations. It will be clinically important and informative if we can estimate QALYs based on measurements of depression severity. Objective: To construct a conversion table from the Patient Health Questionnaire-9 (PHQ-9), the most frequently used depression scale in recent years, to the Euro-Qol Five Dimensions Three Levels (EQ-5D-3L), one of the most commonly used instruments to assess QALYs. Methods: We obtained individual participant data of randomised controlled trials of internet cognitive-behavioural therapy which had administered depression severity scales and the EQ-5D-3L at baseline and at end of treatment. Scores from depression scales were all converted into the PHQ-9 according to the validated algorithms. We used equipercentile linking to establish correspondences between the PHQ-9 and the EQ-5D-3L. Findings: Individual-level data from five trials (total N=2457) were available. Subthreshold depression (PHQ-9 scores between 5 and 10) corresponded with EQ-5D-3L index values of 0.9-0.8, mild major depression (10-15) with 0.8-0.7, moderate depression (15-20) with 0.7-0.5 and severe depression (20 or higher) with 0.6-0.0. A five-point improvement in PHQ-9 corresponded approximately with an increase in EQ-5D-3L score by 0.03 and a ten-point improvement by approximately 0.25. Conclusions and Clinical Implications: The conversion table between the PHQ-9 and the EQ-5D-3L scores will enable fine-grained assessment of burden of depression at its various levels of severity and of impacts of its various treatments.
32.	Gottlieb, Laura (författare) Relational Sensitivity in Participatory Design : Thinking and making together through joint inquiry 2023 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract Participatory design processes can entail involving individuals, groups, and communities in joint inquiry to deliberate on their current situation, imagine alternative futures, and forge possible collaborations. Relational sensitivity – drawing attention to relationships in a given situation – is important when staging (i.e., organising and designing for) and facilitating joint inquiry. It is a valuable concept with which to illuminate and discuss contingent circumstances that may arise and, more generally, to support participation in joint inquiry. This PhD thesis explores and develops views of and a vocabulary for discussing relational sensitivity so as to support practitioners in staging joint inquiry. The thesis includes both a literature review and practice-based studies, applying a research through design approach to discuss relational sensitivity. The practice-based studies examine two participatory design processes: the collaborative designing of a communal space with university students, and the development of shared practices and rituals in a co-working space with professionals from the public sector. The practice-based studies also include nine design experiments in which situations for joint inquiry have been staged in academic contexts and in a museum. Through the literature- and practice-based studies, the thesis addresses two research questions: “How can relational sensitivity be understood when staging situations for joint inquiry?” and “How can the study of relational sensitivity inform practitioners when staging situations for joint inquiry?” Research methods include the use of field notes, journal notes, collective analysis, audio- and video-recordings, and questionnaires.The results include three perspectives from which to understand relational sensitivity when staging joint inquiry: sensitivity to self (e.g., reflexivity, self-awareness, and embodied awareness), sensitivity to intersubjective dynamics (e.g., attunement and responsiveness to group dynamics, affect, emotions, values, trust, and power dynamics), and sensitivity to materiality and process (e.g., the roles of materials, artefacts, and activities in reflection, social cohesion, and diverse contexts, and the role of the body in power dynamics). While relational sensitivity is primarily discussed in relation to practitioners – i.e., those staging joint inquiry – this thesis also discusses the importance of cultivating participants’ awareness of the self and others when staging joint inquiry to collectively support participation.Overall, this research contributes to the research fields of innovation and design and of participatory design by developing knowledge of relational sensitivity and its role in staging situations for joint inquiry. It provides insights into how practitioners can develop, discuss, and study their relational sensitivity and support participants in participatory design processes.

Tidskriftsartikel (refereegranskat)abstract Abstract Transition metals, such as zinc, are essential micronutrients in all organisms, but alsohighly toxic in excessive amounts. Heavy-metal transporting P-type (PIB) ATPases are crucial forhomeostasis, conferring cellular detoxification and redistribution through transport of these ionsacross cellular membranes. No structural information is available for the PIB-4-ATPases, the subclasswith the broadest cargo scope, and hence even their topology remains elusive. Here, we presentstructures and complementary functional analyses of an archetypal PIB-4-ATPase, sCoaT fromSulfitobacter sp. NAS14-1. The data disclose the architecture, devoid of classical so-called heavy-metal-binding domains (HMBDs), and provide fundamentally new insights into the mechanism anddiversity of heavy-metal transporters. We reveal several novel P-type ATPase features, includinga dual role in heavy-metal release and as an internal counter ion of an invariant histidine. We alsoestablish that the turnover of PIB-ATPases is potassium independent, contrasting to many otherP-type ATPases. Combined with new inhibitory compounds, our results open up for efforts in forexample drug discovery, since PIB-4-ATPases function as virulence factors in many pathogens.

The occurrence of stroke may have significant consequences for patients with cardiac conditions and their caregivers and poses a major burden on their lives. Although both cardiac and stroke conditions are highly prevalent, primary stroke prevention in cardiac patients is crucial to avert disabling limitations or even mortality. In addition, specific interventions may be needed in the rehabilitation and follow-up of these patients. However, healthcare systems are often fragmented and are not integrated enough to provide specifically structured and individualised management for the cardiac-stroke patient. Cardiac rehabilitation or secondary prevention services are crucial from this perspective, although referral and attendance rates are often suboptimal. This state of the art review outlines the significance of primary stroke prevention in cardiac patients, highlights specific challenges that cardiac-stroke patients and their caregivers may experience, examines the availability of and need for structured, personalised care, and describes potential implications for consideration in daily practice.

Until recently, global inventories of pollutants from North America Europe and Asia have been used for air quality and climate change modelling in Africa (Bond et al., 2004, Streets et al., 2004, Bond et al., 2007, Klimont et al., 2009, Klimont et al., 2013, Lamarque et al., 2010). Research in air pollution has, however, been lagging far behind in African countries, despite the increasing health and economic impact associated with air pollution in these nations, since systematic monitoring in Africa is often lacking. The health impact of air pollution in African cities has only been sparsely studied: a review from 2018 (Coker and Kizito, 2018) found only 3 studies outside South Africa. Earlier last year, a study showed that air pollution was responsible for 1.1 million deaths across Africa in 2019, with household air pollution—driven largely by solid biofuel used in indoor cook stoves—accounting for 697 000 fatalities (64% of the total), while increased outdoor air pollution claimed 394 000 lives (36% of the total) (Fisher et al., 2021).

We aimed to investigate the risk of cancer in young and older patients with CHD and to evaluate the excess risk of cancer by syndromes, organ transplantation and cardiac surgery. Methods Patients with CHD born between 1930 and 2017 were identified using Swedish Health Registers. Each patient with CHD (n = 89,542) was matched by sex and birth year with ten controls without CHD (n = 890,472) from the Swedish Total Population Register. Findings 4012 patients with CHD (4.5%) and 35,218 controls (4.0%) developed cancer. The median follow-up time was 58.8 (IQR 42.4-69.0) years. The overall cancer risk was 1.23 times higher (95% confidence interval (CI) 1.19 -1.27) in patients with CHD compared with matched controls, and remained significant when patients with syndromes and organ transplant recipients were excluded. The risk of cancer was higher in all CHD age groups, and in patients that underwent cardiac surgery during the first year after birth (Hazard Ratio 1.83; 95% CI 1.32-2.54). The highest risk was found in children (0 -17 years), HR 3.21 (95% CI 2.90-3.56). Interpretation The cancer risk in patients with CHD was 23% higher than in matched controls without CHD.

The objective was to investigate associations between pre- and postnatal antibiotic exposures and the development of allergic manifestations until age 18 months.Methods: We included 1387 mother–child dyads from the prospective, population-based NorthPop birth cohort study. Data on antibiotic exposures in pregnancy and childhood were collected by web-based questionnaires. Until the child turned 18 months old, parents (n = 1219) reported symptoms of wheeze, eczema, and physician-diagnosed asthma; parents (n = 1025) reported physician-diagnosed food allergy. At age 18 months, serum immunoglobulin E levels to inhalant (Phadiatop) and food (Food mix fx5) allergens were determined. Associations were estimated using bivariable and multivariable logistic regressions.Results: Prenatal antibiotic exposure was positively associated with food sensitization in the crude (OR 1.82, 95% CI 1.01–3.26) but not in the adjusted analyses (aOR 1.58, 0.82–3.05). A borderline significant association was found between prenatal exposure and wheeze (aOR 1.56, 0.95–2.57). Postnatal antibiotics were positively associated with wheeze (aOR 2.14, 1.47–3.11), asthma (aOR 2.35, 1.32–4.19), and eczema (aOR 1.49, 1.07–2.06). Postnatal antibiotics were negatively associated with food sensitization (aOR 0.46, 95% CI 0.25–0.83) but not with food allergy nor sensitization to inhalants.Conclusion: Pre- and postnatal antibiotic exposure demonstrated positive associations with allergic manifestations and the former also with food sensitization. In contrast, there was a negative association between postnatal antibiotics and food sensitization. Food sensitization is often transient but may precede respiratory allergies. Future studies should investigate the relationship between antibiotic exposure and food sensitization later in childhood.

(författare) Analysis and modelling of mistriage in the Stockholm stroke triage system 2022 Ingår i: European Stroke Journal. - : Sage Publications. - 2396-9873 .- 2396-9881. ; 7:2, s. 126-133 Tidskriftsartikel (refereegranskat)abstract Introduction: The Stockholm Stroke Triage System (SSTS) is a prehospital triage system for detection of patients eligible for endovascular thrombectomy (EVT). Assessment of hemiparesis combined with ambulance-hospital teleconsultation is used to route patients directly to the thrombectomy centre. Some patients are not identified and require secondary transport for EVT (undertriage) while others taken to the thrombectomy centre do not undergo EVT (overtriage). The aims of this study were to characterize mistriaged patients, model for and evaluate alternative triage algorithms.Patients and methods: Patients with suspected stroke transported by priority 1 ground ambulance between October 2017 and October 2018 (n = 2905) were included. Three triage algorithms were modelled using prehospital data. Decision curve analysis was performed to calculate net benefit (correctly routing patients for EVT without increasing mistriage) of alternative models vs SSTS.Results: Undertriage for EVT occurred in n = 35/2582 (1.4%) and overtriage in n = 239/323 (74.0%). Compared to correct thrombectomy triages, undertriaged patients were younger and had lower median NIHSS (10 vs 18), despite 62.9% with an M1 occlusion. In overtriaged patients, 77.0% had a stroke diagnosis (29.7% haemorrhagic). Hemiparesis and FAST items face and speech were included in all models. Decision curve analysis showed highest net benefit for SSTS for EVT, but lower for large artery occlusion (LAO) stroke.Discussion: Undertriaged patients had lower NIHSS, likely due to better compensated proximal occlusions. SSTS was superior to other models for identifying EVT candidates, but lacked information allowing comparison to other prehospital scales.Conclusion: Using prehospital data, alternative models did not outperform the SSTS in finding EVT candidates.

In the Stockholm Region (6 primary stroke centers, 1 EVT center), SSTS implementation in October 2017 reduced onset-to-EVT time by 69 minutes. We compared clinical outcomes before and after implementation of SSTS in an observational study.METHODS: We prospectively recruited patients transported by Code Stroke ambulance within the Stockholm region under the SSTS, treated with EVT during October 2017 to October 2019, and compared to EVT patients from 2 previous years.OUTCOMES: shift in modified Rankin Scale (mRS) scores, mRS score 0 to 1, mRS score 0 to 2, and death (all 3 months), National Institutes of Health Stroke Scale (NIHSS) score change 24-hour post-EVT, recanalization (Thrombolysis in Cerebral Infarction 2b-3), and symptomatic intracranial hemorrhage. mRS outcomes were adjusted for age and baseline NIHSS.RESULTS: Patients with EVT in the SSTS group (n=244) were older and had higher baseline NIHSS versus historical controls (n=187): median age 74 (interquartile range, 63-81) versus 71 (61-78); NIHSS score 17 (11.5-21) versus 15 (10-20). During SSTS, median onset-to-puncture time was 136 versus 205 minutes (P<0.001). Adjusted common odds ratio for lower mRS in SSTS patients was 1.7 (95% CI, 1.2-2.3) versus controls. During SSTS, 83/240 (34.6%) versus 44/186 (23.7%) reached 3-month mRS score 0 to 1 (P=0.014), adjusted common odds ratio 2.3 (95% CI, 1.4-3.6). Median NIHSS change 24-hour post-EVT was 6 versus 4 (P=0.005). Differences in Thrombolysis in Cerebral Infarction, symptomatic intracranial hemorrhage, and death were nonsignificant.CONCLUSIONS: With an onset to arterial puncture time reduction by 69 minutes, outcomes in thrombectomy-treated patients improved significantly after region-wide large artery occlusion triage system implementation. These results warrant replication studies in other geographic and organizational circumstances.

(författare) Inter-centre comparison of data on surgery and speech outcomes at 5 years of age based on the Swedish quality registry for patients born with cleft palate with or without cleft lip 2022 Ingår i: BMC Pediatrics. - : Springer Science and Business Media LLC. - 1471-2431. ; 22:1 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: The objective of the Swedish cleft lip and palate registry (CLP registry) is to promote quality control, research and improvement of treatment, by the comparison of long-term results. The aim was to compare data from the CLP registry among the six treatment centres, regarding data on surgery and speech outcomes at 5 years of age.METHODS: The participants were 430 children born in Sweden from 2009 to 2014, with cleft palate with or without cleft lip and without known syndromes and/or additional malformations. The number of primary and secondary palatal surgeries up to 5 years of age, timing of the last primary palatal surgery, percentage consonants correct, percentage non-oral speech errors and perceived velopharyngeal competence at 5 years were assessed. Multivariable binary logistic regression adjusted for sex and cleft type was used to compare results between the six centres.RESULTS: At one centre (centre 4), the palate was closed in one to three stages, and at the remaining centres in one or two stages. At centre 4, more children underwent a higher number of palatal surgeries, and the last primary palatal surgery was performed at a higher age. Children in centre 4 were also less likely to achieve ≥86% correct consonants (OR = 0.169, P = < 0.001), have no non-oral speech errors (OR = 0.347, P = < 0.001), or have competent or marginally incompetent velopharyngeal competence (OR = 0.244, P = < 0.001), compared to the average results of the other centres. No clear association between patient volume and speech outcome was observed.CONCLUSIONS: The results indicated the risk of a negative speech result if the last primary palatal surgery was performed after 25 months of age. Whether the cleft in the palate was closed in one or two stages did not affect speech outcome. The Swedish CLP registry can be used for open comparisons of treatment results to provide the basis for improvements of treatment methods. If deviating negative results are seen consistently at one centre, this information should be acted upon by further investigation and analysis, making changes to the treatment protocol as needed.

(författare) Ice-nucleating ability of particulate emissions from solid-biomass-fired cookstoves : An experimental study 2020 Ingår i: Atmospheric Chemistry and Physics. - : Copernicus GmbH. - 1680-7316 .- 1680-7324. ; 20:8, s. 4951-4968 Tidskriftsartikel (refereegranskat)abstract This research was part of the Salutary Umeå Study of Aerosols in Biomass Cookstove Emissions (SUSTAINE) laboratory experiment campaign. We studied ice-nucleating abilities of particulate emissions from solid-fuel-burning cookstoves, using a portable ice nuclei counter, Spectrometer Ice Nuclei (SPIN). These emissions were generated from two traditional cookstove types commonly used for household cooking in sub-Saharan Africa and two advanced gasifier stoves under research to promote sustainable development alternatives. The solid fuels studied included biomass from two different African tree species, Swedish softwood and agricultural residue products relevant to the region. Measurements were performed with a modified version of the standard water boiling test on polydisperse samples from flue gas during burning and size-selected accumulation mode soot particles from a 15 m3 aerosol-storage chamber. The studied soot particle sizes in nanometers were 250, 260, 300, 350, 400, 450 and 500. From this chamber, the particles were introduced to water-supersaturated freezing conditions (-32 to-43 °C) in the SPIN. Accumulation mode soot particles generally produced an ice-activated fraction of 10-3 in temperatures 1-1.5 °C higher than that required for homogeneous freezing at fixed RHw D 115 %. In five special experiments, the combustion performance of one cookstove was intentionally modified. Two of these exhibited a significant increase in the icenucleating ability of the particles, resulting in a 10-3 ice activation at temperatures up to 5.9 °C higher than homogeneous freezing and the observed increased ice-nucleating ability. We investigated six different physico-chemical properties of the emission particles but found no clear correlation between them and increasing ice-nucleating ability. We conclude that the freshly emitted combustion aerosols form ice via immersion and condensation freezing at temperatures only moderately above homogeneous freezing conditions.

(författare) Properties and emission factors of cloud condensation nuclei from biomass cookstoves - Observations of a strong dependency on potassium content in the fuel 2021 Ingår i: Atmospheric Chemistry And Physics. - : Nicolaus Copernicus University Press. - 1680-7316 .- 1680-7324. ; 21:10, s. 8023-8044 Tidskriftsartikel (refereegranskat)abstract Residential biomass combustion is a significant source of aerosol particles on regional and global scales influencing climate and human health. The main objective of the current study was to investigate the properties of cloud condensation nuclei (CCN) emitted from biomass burning of solid fuels in different cookstoves mostly of relevance to sub- Saharan east Africa.The traditional three-stone fire and a rocket stove were used for combustion of wood logs of Sesbania and Casuarina with birch used as a reference. A natural draft and a forced-draft pellet stove were used for combustion of pelletised Sesbania and pelletised Swedish softwood alone or in mixtures with pelletised coffee husk, rice husk or water hyacinth. The CCN activity and the effective density were measured for particles with mobility diameters of v65, v100 and v200 nm, respectively, and occasionally for 350 nm particles. Particle number size distributions were measured online with a fast particle analyser. The chemical composition of the fuel ash was measured by application of standard protocols.The average particle number size distributions were by number typically dominated by an ultrafine mode, and in most cases a soot mode was centred around a mobility diameter of v150 nm. The CCN activities decreased with increasing particle size for all experiments and ranged in terms of the hygroscopicity parameter, from v0:1 to v0:8 for the ultrafine mode and from v0:001 to v0:15 for the soot mode. The CCN activity of the ultrafine mode increased (i) with increasing combustion temperature for a given fuel, and (ii) it typically increased with increasing potassium concentration in the investigated fuels. The primary CCN and the estimated particulate matter (PM) emission factors were typically found to increase significantly with increasing potassium concentration in the fuel for a given stove. In order to link CCN emission factors to PM emission factors, knowledge about stove technology, stove operation and the inorganic fuel ash composition is needed. This complicates the use of ambient PM levels alone for estimation of CCN concentrations in regions dominated by biomass combustion aerosol, with the relation turning even more complex when accounting for atmospheric ageing of the aerosol.

(författare) Lifestyle counseling in patients with hypertension in primary health care and its association with antihypertensive pharmacotherapy 2024 Ingår i: The Journal of Clinical Hypertension. - 1524-6175 .- 1751-7176. Tidskriftsartikel (refereegranskat)abstract The study aimed to investigate differences in hypertensive- and cardio-preventive pharmacotherapy depending on if patients with hypertension received lifestyle counseling or not, including the difference between men and women. Data from the Region Stockholm VAL database was used to identify all patients with a hypertension diagnosis and had visited a primary health care center within the past five years. Data included registered diagnoses, pharmacotherapy, and codes for lifestyle counseling. Logistic regression adjusted for age and comorbidity (diabetes, stroke, coronary heart disease, atrial fibrillation, gout, obesity, heart failure) was used, presenting results as odds ratios (OR) with 99% confidence interval (CI). The study included 130,030 patients with hypertension; 63,402 men and 66,628 women. Patients receiving recommended lifestyle counseling were more frequently treated with three or more hypertensive drugs: women OR 1.38 (1.31, 1.45) and men = 1.36 (1.30, 1.43); certain drug classes: calcium antagonists: women 1.09 (1.04, 1.14) and men 1.11 (1.06, 1.16); thiazide diuretics: women 1.26 (1.20, 1.34) and men 1.25 (1.19, 1.32); and aldosterone antagonists: women 1.25 (1.12, 1.41) and men 1.49 (1.34, 1.65). Patients receiving recommended level of lifestyle counseling with concomitant coronary heart disease, atrial fibrillation, diabetes, or stroke were more frequently treated with statins than those who did not. Further, recommended lifestyle counseling was significantly associated with anticoagulant treatment in patients with atrial fibrillation. Lifestyle counseling according to recommendations in national guidelines was significantly associated with a more thorough pharmacological treatment of hypertension, statins, and antithrombotic drugs as well as anticoagulants, in both men and women.

(författare) Implementation of a Prehospital Stroke Triage System Using Symptom Severity and Teleconsultation in the Stockholm Stroke Triage Study 2020 Ingår i: JAMA Neurology. - : American Mathematical Society (AMS). - 2168-6149 .- 2168-6157. ; 77:6, s. 691-699 Tidskriftsartikel (refereegranskat)abstract Importance: To our knowledge, it is unknown whether a prehospital stroke triage system combining symptom severity and teleconsultation could accurately select patients for primary stroke center bypass and hasten delivery of endovascular thrombectomy (EVT) without delaying intravenous thrombolysis (IVT).Objective: To evaluate the predictive performance of the newly implemented Stockholm Stroke Triage System (SSTS) for large-artery occlusion (LAO) stroke and EVT initiation. Secondary objectives included evaluating whether the Stockholm Stroke Triage System shortened onset-to-puncture time for EVT and onset-to-needle time (ONT) for IVT.Design, Setting, and Participants: This population-based prospective cohort study conducted from October 2017 to October 2018 across the Stockholm region (Sweden) included patients transported by first-priority ("code stroke") ambulance to the hospital for acute stroke suspected by an ambulance nurse and historical controls (October 2016-October 2017). Exclusion criteria were in-hospital stroke and helicopter or private transport. Of 2909 eligible patients, 4 (0.14%) declined participation.Exposures: Patients were assessed by ambulance nurses with positive the face-arm-speech-time test or other stroke suspicion and were evaluated for moderate-to-severe hemiparesis (≥2 National Institutes of Health stroke scale points each on the ipsilateral arm and leg [A2L2 test]). If present, the comprehensive stroke center (CSC) stroke physician was teleconsulted by phone for confirmation of stroke suspicion, assessment of EVT eligibility, and direction to CSC or the nearest primary stroke center. If absent, the nearest hospital was prenotified.Main Outcomes and Measures: Primary outcome: LAO stroke. Secondary outcomes: EVT initiation, onset-to-puncture time, and ONT. Predictive performance measures included sensitivity, specificity, positive and negative predictive values, the overall accuracy for LAO stroke, and EVT initiation.Results: We recorded 2905 patients with code-stroke transports (1420 women [49%]), and of these, 323 (11%) had A2L2+ teleconsultation positive results and were triaged for direct transport to CSC (median age, 73 years [interquartile range (IQR), 64-82 years]; 55 women [48%]). Accuracy for LAO stroke was 87% (positive predictive value, 41%; negative predictive value, 93%) and 91% for EVT initiation (positive predictive value, 26%; negative predictive value, 99%). Endovascular thrombectomy was performed for 84 of 323 patients (26%) with triage-positive results and 35 of 2582 patients (1.4%) with triage-negative results. In EVT cases with a known onset time (77 [3%]), the median OPT was 137 minutes (IQR, 118-180; previous year, 206 minutes [IQR, 160-280]; n = 75) (P < .001). The regional median ONT (337 [12%]) was unchanged at 115 minutes (IQR, 83-164; previous year, 115 minutes [IQR, 85-161]; n = 360) (P = .79). The median CSC IVT door-to-needle time was 13 minutes (IQR, 10-18; 116 [4%]) (previous year, 31 minutes [IQR, 19-38]; n = 45) (P < .001).Conclusions and Relevance: The Stockholm Stroke Triage System, which combines symptom severity and teleconsultation, results in markedly faster EVT delivery without delaying IVT.
46.	McCarrick, Sarah, et al. (författare) Toxicity of particles derived from combustion of Ethiopian traditional biomass fuels in human bronchial and macrophage-like cells 2024 Ingår i: Archives of Toxicology. - 0340-5761. ; 98:5, s. 1515-1532 Tidskriftsartikel (refereegranskat)abstract The combustion of traditional fuels in low-income countries, including those in sub-Saharan Africa, leads to extensive indoor particle exposure. Yet, the related health consequences in this context are understudied. This study aimed to evaluate the in vitro toxicity of combustion-derived particles relevant for Sub-Saharan household environments. Particles (< 2.5 µm) were collected using a high-volume sampler during combustion of traditional Ethiopian biomass fuels: cow dung, eucalyptus wood and eucalyptus charcoal. Diesel exhaust particles (DEP, NIST 2975) served as reference particles. The highest levels of particle-bound polycyclic aromatic hydrocarbons (PAHs) were found in wood (3219 ng/mg), followed by dung (618 ng/mg), charcoal (136 ng/mg) and DEP (118 ng/mg) (GC–MS). BEAS-2B bronchial epithelial cells and THP-1 derived macrophages were exposed to particle suspensions (1–150 µg/mL) for 24 h. All particles induced concentration-dependent genotoxicity (comet assay) but no pro-inflammatory cytokine release in epithelial cells, whereas dung and wood particles also induced concentration-dependent cytotoxicity (Alamar Blue). Only wood particles induced concentration-dependent cytotoxicity and genotoxicity in macrophage-like cells, while dung particles were unique at increasing secretion of pro-inflammatory cytokines (IL-6, IL-8, TNF-α). In summary, particles derived from combustion of less energy dense fuels like dung and wood had a higher PAH content and were more cytotoxic in epithelial cells. In addition, the least energy dense and cheapest fuel, dung, also induced pro-inflammatory effects in macrophage-like cells. These findings highlight the influence of fuel type on the toxic profile of the emitted particles and warrant further research to understand and mitigate health effects of indoor air pollution.

(författare) Plasma proteome profiling of cardiotoxicity in patients with diffuse large B-cell lymphoma 2021 Ingår i: Cardio-Oncology. - : Springer Science and Business Media LLC. - 2057-3804. ; 7:1 Tidskriftsartikel (refereegranskat)abstract Background Cardiovascular toxicity is a notorious complication of doxorubicin (DXR) therapy for diffuse large B-cell lymphoma (DLBCL). Although surveillance of well-known biological markers for cardiovascular disease (CVD) as NTproBNP and Troponins may be helpful, there are no established markers to monitor for evolving CVD during treatment. New possibilities have arisen with the emergence of newer techniques allowing for analysis of plasma proteins that can be associated with cardiovascular disease. Proximity Extension Assay is one of them. Objectives We aimed to illustrate the incidence of CVD in DLBCL patients treated with DXR and to establish whether there are plasma proteins associated with pre-existing or emerging CVD. Methods In 95 patients, 182 different proteins from OLINK panels, NTproBNP, Troponin I and CRP were assessed prior to, during and after treatment. For comparison, samples from controls were analyzed. Results In the DLBCL cohort, 33.3% had pre-treatment CVD compared to 5.0% in the controls and 23.2% developed new CVD. Of the 32.6% who died during follow up, CVD was the cause in 4 patients. Spondin-1 (SPON-1) correlated to pre-treatment CVD (1.22 fold change, 95% CI 1.10-1.35, p = 0.00025, q = 0.045). Interleukin-1 receptor type 1 (IL-1RT1) was associated to emerging CVD (1.24 fold change, 95% CI 1.10-1.39, p = 0.00044, q = 0.082). Conclusion We observed a higher prevalence of CVD in DLBCL patients compared to controls prior to DXR therapy. Two proteins, SPON-1 and IL-1RT1, were related to pre-existing and emerging CVD in DXR treated patients. If confirmed in larger cohorts, IL-1RT1 may emerge as a reliable biomarker for unfolding CVD in DLBCL.

(författare) Piezo1 activation attenuates thrombin-induced blebbing in breast cancer cells 2022 Ingår i: Journal of Cell Science. - : The Company of Biologists. - 0021-9533 .- 1477-9137. ; 135:7 Tidskriftsartikel (refereegranskat)abstract Cancer cells exploit a variety of migration modes to leave primary tumors and establish metastases, including amoeboid cell migration, which is typically reliant on bleb formation. Here we demonstrate that thrombin induces dynamic blabbing in the MDA-MB-231 breast cancer cell line and confirm that protease-activated receptor 1 (PAR1) activation is sufficient to induce this effect. Cell confinement has been implicated as a driving force in bleb-based migration. Unexpectedly, we found that gentle contact compression, exerted using a custom built 'cell press' to mechanically stimulate cells, reduced thrombin-induced blebbing. Thrombin-induced blebbing was similarly attenuated using the small molecule Yoda1, an agonist of the mechanosensitive Ca2+ channel Piezo1, and this attenuation was impaired in Piezo1-depleted cells. Additionally, Piezo1 activation suppressed thrombin-induced phosphorylation of ezrin, radixin and moesin (ERM) proteins, which are implicated in the blabbing process. Our results provide mechanistic insights into Piezo1 activation as a suppressor of dynamic blebbing, specifically that which is induced by thrombin.

(författare) Lillla Barnsmärtguiden : ett evidensbaserat verktyg mot vaccinationssmärta 2021 Konferensbidrag (refereegranskat)abstract Bakgrund: Trots kunskap om hur små barn påverkas negativt av smärtsamma procedurer och tillgången till effektiva motåtgärder genomförs mängder av vaccinationer och andra injektioner utan tillräcklig smärtlindring. Lilla Barnsmärtguiden utvecklades därför som ett webbaserat verktyg till hjälp för personal som injicerar barn i åldern 0-6 år.Material och metod: Med stöd av AbbVie AB genomfördes två workshops med sjuksköterskor med stor vana att ge injektioner till barn. Genom föreläsningar, gruppdiskussioner och s.k. graphic recording formulerades förslag till åtgärder i områdena det späda barnet, det lilla barnet, det stora barnet, föräldrarna samt personalen. Utifrån detta utformade arbetsgruppen text och bild för en webbplats med funktionalitet för såväl dator som läsplatta och mobiltelefon. Innehåll och design testades mot en grupp sjuksköterskor inom barnhälsovården och specialistsjukvården. Samtidigt utformades informationsmaterial för att sprida kännedom om Lilla Barnsmärtguiden.Resultat: Den färdiga webbplatsen publicerades med Örebro universitet som utgivare, på www.lillabarnsmartguiden.se med de fyra sektionerna förberedelser, under besöket, barn i olika åldrar samt vårdnadshavaren. Under dessa rubriker ges förslag på farmakologiska och icke-farmakologiska åtgärder som kan användas för att minska smärta och obehag vid vaccinationer och andra injektioner. Hänvisning till nyckelreferenser görs för de som vill läsa vidare.Lanseringen av Lilla Barnsmärtguiden fick ett bra genomslag i media vilket bl.a. ledde till flera chat-sessioner hos Sveriges television. Under de fyra första månaderna nåddes över 5 500 unika besökare.Slutsats: Barn som genomgår vaccinationer och andra injektioner får otillräcklig smärtlindring. Lilla Barnsmärtguiden möter ett behov av information och stöd till personal som genomför de smärtsamma procedurerna.

(författare) Cooking and electronic cigarettes leading to large differences between indoor and outdoor particle composition and concentration measured by aerosol mass spectrometry 2020 Ingår i: Environmental Sciences: Processes and Impacts. - : Royal Society of Chemistry (RSC). - 2050-7895 .- 2050-7887. ; 22:6, s. 1382-1396 Tidskriftsartikel (refereegranskat)abstract We spend about two thirds of our time in private homes where airborne particles of indoor and outdoor origins are present. The negative health effects of exposure to outdoor particles are known. The characteristics of indoor airborne particles, though, are not well understood. This study assesses the differences in chemical composition of PM1 (<1 μm) inside and outside of an occupied Swedish residence in real time with a High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS) and an Aethalometer. The chemical composition and concentration of particles indoors showed large differences compared to outdoors. The average indoor concentration was 15 μg m-3 and was higher than the outdoor 7 μg m-3. Organics dominated indoor particle composition (86% of the total mass) and originated from indoor sources (cooking, e-cigarette vaping). The average indoor to outdoor ratios were 5.5 for organic matter, 1.0 for black carbon, 0.6 for sulphate, 0.1 for nitrate, 0.2 for ammonium and 0.2 for chloride. The occupancy time accounted for 97% of the total measured period. Four factors were identified in the source apportionment of organic particle fraction by applying positive matrix factorization (PMF): two cooking factors, one e-cigarette factor and one outdoor contribution (OOA) organic factor penetrated from outside.
