    Contributions of mean and shape of blood pressure distribution to worldwide trends and variations in raised blood pressure: a pooled analysis of 1018 population-based measurement studies with 88.6 million participants2018In: International Journal of Epidemiology, ISSN 0300-5771, E-ISSN 1464-3685Article in journal (Refereed)
    Abstract [en]

    Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions of these two phenomena to the worldwide trends in the prevalence of raised blood pressure.

    Methods: We pooled 1018 population-based studies with blood pressure measurements on 88.6 million participants from 1985 to 2016. We first calculated mean systolic blood pressure (SBP), mean diastolic blood pressure (DBP) and prevalence of raised blood pressure by sex and 10-year age group from 20–29 years to 70–79 years in each study, taking into account complex survey design and survey sample weights, where relevant. We used a linear mixed effect model to quantify the association between (probittransformed) prevalence of raised blood pressure and age-group- and sex-specific mean blood pressure. We calculated the contributions of change in mean SBP and DBP, and of change in the prevalence-mean association, to the change in prevalence of raised blood pressure.

    Results: In 2005–16, at the same level of population mean SBP and DBP, men and women in South Asia and in Central Asia, the Middle East and North Africa would have the highest prevalence of raised blood pressure, and men and women in the highincome Asia Pacific and high-income Western regions would have the lowest. In most region-sex-age groups where the prevalence of raised blood pressure declined, one half or more of the decline was due to the decline in mean blood pressure. Where prevalence of raised blood pressure has increased, the change was entirely driven by increasing mean blood pressure, offset partly by the change in the prevalence-mean association.

    Conclusions: Change in mean blood pressure is the main driver of the worldwide change in the prevalence of raised blood pressure, but change in the high-blood-pressure tail of the distribution has also contributed to the change in prevalence, especially in older age groups.

    Are circumcised men safer sex partners?: Findings from the HAALSI cohort in rural South Africa2018In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, no 8, article id e0201445Article in journal (Refereed)
    Abstract [en]

    Introduction: The real-world association between male circumcision and HIV status has important implications for policy and intervention practice. For instance, women may assume that circumcised men are safer sex partners than non-circumcised men and adjust sexual partnering and behavior according to these beliefs. Voluntary medical male circumcision (VMMC) is highly efficacious in preventing HIV acquisition in men and this biological efficacy should lead to a negative association between circumcision and HIV. However, behavioral factors such as differential selection into circumcision based on current HIV status or factors associated with future HIV status could reverse the association. Here, we examine how HIV prevalence differs by circumcision status in older adult men in a rural South African community, a non-experimental setting in a time of expanding VMMC access.

    Methods: We analyzed data collected from a population-based sample of 2345 men aged 40 years and older in a rural community served by the Agincourt Health and socio-Demographic Surveillance System site in Mpumalanga province, South Africa. We describe circumcision prevalence and estimate the association between circumcision and laboratory-confirmed HIV status with log-binomial regression models.

    Results: One quarter of older men reported circumcision, with slightly more initiation-based circumcisions (56%) than hospital-based circumcisions (44%). Overall, the evidence did not suggest differences in HIV prevalence between circumcised and uncircumcised men; however, those who reported hospital-based circumcision were more likely to test HIV-positive [PR (95% CI): 1.28 (1.03, 1.59)] while those who reported initiation-based circumcision were less likely to test HIV-positive [PR (95% CI): 0.68 (0.51, 0.90)]. Effects were attenuated, but not reversed after adjustment for key covariates.

    Conclusions: Medically circumcised older men in a rural South African community had higher HIV prevalence than uncircumcised men, suggesting that the effect of selection into circumcision may be stronger than the biological efficacy of circumcision in preventing HIV acquisition. The impression given from circumcision policy and dissemination of prior trial findings that those who are circumcised are safer sex partners may be incorrect in this age group and needs to be countered by interventions, such as educational campaigns.

    Multidisciplinary design automation: Working with product model extensions2018Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Being able to efficiently and effectively provide custom products has been identified as a competitive advantage for manufacturing organizations. Product configuration has been shown to be an effective way of achieving this through a modularization, product platform and product family development approach. A core assumption behind product configuration is that the module variants and their constraints can be explicitly defined as product knowledge in terms of geometry and configuration rules. This is not always the case, however. Many companies require extensive engineering to develop each module variant and cannot afford to do so in order to meet potential customer requirements within a predictable future. Instead, they try to implicitly define the module variants in terms of the process for how they can be realized. In this way they can realize module variants on demand efficiently and effectively when the customer requirements are better defined, and the development can be justified by the increased probability of profiting from the outcome.

    Design automation, in its broadest definition, deals with computerized engineering support by effectively and efficiently utilizing pre-planned reusable assets to progress the design process. There have been several successful implementations reported in the literature, but a widespread use is yet to be seen. It deals with the explicit definition of engineering process knowledge, which results in a collection of methods and models that can come in the form of computer scripts, parametric CADmodels, template spreadsheets, etc. These methods and models are developed using various computer tools and maintained within the different disciplines involved, such as geometric modeling, simulation, or manufacturing, and are dependent on each other through the product model. To be able to implement, utilize, and manage design automation systems in or across multiple disciplines, it is important to first understand how the disciplinary methods and models are dependent on each other through the product model and then how these relations should be constructed to support the users without negatively affecting other aspects, such as modeling flexibility, minimum documentation, and software tool independence.

    To support the successful implementation and management of design automation systems the work presented here has focused on understanding how some digital product model constituents are, can, and, to some extent, should be extended to concretize relations between methods and models from different tools and disciplines. It has been carried out by interviewing Swedish industrial companies, performing technical reviews, performing literature reviews, and developing prototypes, which has resulted in an increased understanding and the consequent development of a conceptual framework that highlights aspects relating to the choice of extension techniques.

    What prevents midwifery quality care in Bangladesh? A focus group enquiry with midwifery students2018In: BMC Health Services Research, ISSN 1472-6963, E-ISSN 1472-6963, Vol. 18, no 1, article id 639Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: With professional midwives being introduced in Bangladesh in 2013, the aim of this study was to describe midwifery students perceptions on midwives' realities in Bangladesh, based on their own experiences.

    METHOD: Data were collected through 14 focus group discussions that included a total of 67 third-year diploma midwifery students at public nursing institutes/colleges in different parts of Bangladesh. Data were analyzed deductively using an analytical framework identifying social, professional and economical barriers to the provision of quality care by midwifery personnel.

    RESULTS: The social barriers preventing midwifery quality care falls outside the parameters of Bangladeshi cultural norms that have been shaped by beliefs associated with religion, society, and gender norms. This puts midwives in a vulnerable position due to cultural prejudice. Professional barriers include heavy workloads with a shortage of staff who were not utilized to their full capacity within the health system. The reason for this was a lack of recognition in the medical hierarchy, leaving midwives with low levels of autonomy. Economical barriers were reflected by lack of supplies and hospital beds, midwives earning only low and/or irregular salaries, a lack of opportunities for recreation, and personal insecurity related to lack of housing and transportation.

    CONCLUSION: Without adequate support for midwives, to strengthen their self-confidence through education and through continuous professional and economic development, little can be achieved in terms of improving quality care of women during the period around early and late pregnancy including childbirth.The findings can be used for discussions aimed to mobilize a midwifery workforce across the continuum of care to deliver quality reproductive health care services. No matter how much adequate support is provided to midwives, to strengthen their self-confidence through education, continuous professional and economic development, addressing the social barriers is a prerequisite for provision of quality care.

    Medie- och informationskunnighet (MIK) i den digitala tidsåldern En demokratifråga -Kartläggning, analys, reflektioner2018Conference proceedings (editor) (Other academic)
    Abstract [sv]

    Många av dagens samhällsfrågor är kopplade till digitaliseringen och dess konsekvenser. Inte minst ställs nya krav på medborgarna i en digitaliserad medie- och kommunikationskultur utifrån ett demokrati-perspektiv. Det är mot en sådan bakgrund denna kunskapsöversikt har utarbetats.Medie- och informationskunnighet (MIK) är tveklöst en nyckelkunskap i dagens samhälle – om det råder stor samstämmighet bland berörda aktörer. Men hur ett arbete rörande MIK ska kunna organiseras i Sverige för att nå reella resultat har diskuterats i flera år utan att ett samlat uttryck från politiken har kommit till stånd. En utgångspunkt i detta arbete har varit att betrakta MIK i ett helhets-perspektiv – som en del av många olika politikområden och inte minst demokratipolitiken. Samtidigt måste den nationella politiken mer än någonsin ha ett ömsesidigt utbyte med såväl europeisk som global politik. I dagens komplexa samhälle krävs också en konstruktiv dialog och samverkan mellan olika berörda aktörer inom såväl politiken som medieföretagen och det civila samhället för att nå fruktbara resultat. Kunskapsöversikten söker fånga utmaningar och möjligheter rörande MIK i digitaliseringens tid. Den baseras på en kartläggning av MIK i Sverige – insatser och aktörer, nedslag i såväl forskningen som praktiken samt europeiska och internationella utblickar. I ett avslutande kapitel redovisas de konklusioner som kan dras från kunskapsöversiktens olika delar och ett framåtblickande scenario presenteras.

    Injectable Composite Hydrogels Based on Metal-Ligand Assembly for Biomedical Applications2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis presents new strategies to construct injectable hydrogels and their various biomedical applications, such as 3D printing, regenerative medicine and drug delivery. These hydrogels cross-linked by dynamic metal-ligand coordination bonds exhibit shear-thinning and self-healing properties, resulting in the unlimited time window for injection. Compared with non-dynamic networks based on chemically reactive liquid polymer precursors that forms covalent bond during and/or post-injection, our injectable hydrogels with dynamic cross-linkages can be injected from an already cross-linked hydrogel state. 

    Hyaluronic acid (HA) has been selected as the polymer due to its high biocompatibility and biodegradability. HA has been modified by attaching the bisphosphonates (BP) functionality as ligands for chelation of the metal ions or metal salts to form coordination cross-linkages. In the first part of this thesis, I presented the different chemical approaches to synthesize BP-modified HA (HA-BP) derivatives as well as HA derivatives dually modified with BP and acrylamide (Am) groups (Am-HA-BP). The structures of HA-BP derivatives were confirmed by NMR characterizations, e.g. by the peak at 2.18 ppm for methylene protons adjacent to the bridging carbon of BP in 1H-NMR spectrum and phosphorus peak at 18.27 ppm in 31P-NMR spectrum, respectively. In the next part, the hydrogels were constructed by simple mixing of HA-BP or Am-HA-BP solution with Ca2+ ions (Paper I), Ag+ ions (Paper II),  calcium phosphonate coated silk microfibers (CaP@mSF) (Paper III), and magnesium silicate (MgSiO3) nanoparticles (Paper IV). The presented hydrogels exhibited dynamic features determined by reversible nature of coordination networks formed between of BP moieties of HA-BP or Am-HA-BP and metal ions or metal salts on the surface of the inorganic particles. Dynamic properties were characterized by rheological strain sweep experiments and strain-alternating time sweep experiments. Additionally, reversible coordination hydrogels were demonstrated to be further covalently cross-linked by UV light to form a secondary cross-linkage, allowing an increase of the strength and modulus of the hydrogels. In the last part of this thesis, biomedical applications of these hydrogels were presented. Am-HA-BP•Ca2+ hydrogel was extruded, using home-made 3D printer, then fixed by UV irradiation to fabricate multi-layered 3D tube-like construct (Paper I). In full-thickness skin defects of rat model, HA-BP•Ag+ hydrogel accelerated the wound healing process and increased thickness of newly-regenerated epidermal layer (Paper II). In the rat cranial critical defect model, double cross-linked Am-HA-BP•CaP@mSF hydrogel induced new bone formation without addition of biological factors and cells (Paper III). The anti-cancer drug loaded hydrogel was also prepared by mixing of the drug loaded MgSiO3 nanoparticles with HA-BP solution. The released particles from the hydrogel were shown to be taken up by cancer cells to induce a toxic response (Paper IV).

    In summary, this thesis presents metal-ligand coordination chemical strategies to build injectable hydrogels with dynamic cross-linking resulting in time-independent injection behavior. These hydrogels open new possibilities for use in biomedical areas.

    Involvement that makes an impact on healthcare: Perceptions of the Swedish public2018In: Scandinavian Journal of Public Health, ISSN 1403-4948, E-ISSN 1651-1905, Vol. 46, no 4, p. 471-477Article in journal (Refereed)
    Abstract [en]

    Aim: Participation and influence in society' is the first of 11 objective domains in Swedish public health policy. The aim of this article is to investigate the views of the Swedish general population on the impact of a range of health participation activities, and whether these views were associated with sociodemographic characteristics. Methods: The study utilizes a national representative survey of the Swedish population, aged 15 years and over (n = 1500). Results: Apart from voting in regional elections - which most of the respondents believed to be an influential way to make improvements in healthcare (74%) - respondents believed more in individual patient activities than activities associated with adopting a citizen role and acting collectively. A majority of respondents believed in the impact of replying to patient surveys (67%), making a complaint (61%), talking directly to staff (58%) or changing their healthcare provider (54%). Fewer believed in the impact of joining a patient organization (46%), taking part in a citizen council (35%) or joining a political party (34%). Beliefs in impact increased with educational attainment and decreased with age. Conclusions: The results suggest people have more confidence in the impact of participating as individual patients rather than collectively and as citizens. To ensure that activities enable participation and influence in society', complementary opportunities for collective involvement that also take into account under-represented voices such as those with a low level of education need to be developed.

    Electrostatic interactions in soft particle systems: mesoscale simulations of ionic liquids2018In: Soft Matter, ISSN 1744-683X, E-ISSN 1744-6848, Vol. 14, no 21, p. 4252-4267Article in journal (Refereed)
    Abstract [en]

    Computer simulations provide a unique insight into the microscopic details, molecular interactions and dynamic behavior responsible for many distinct physicochemical properties of ionic liquids. Due to the sluggish and heterogeneous dynamics and the long-ranged nanostructured nature of ionic liquids, coarse-grained mesa-scale simulations provide an indispensable complement to detailed first-principles calculations and atomistic simulations allowing studies over extended length and time scales with a modest computational cost. Here, we present extensive coarse-grained simulations on a series of ionic liquids of the 1-alkyl-3-methylimidazolium (alkyl = butyl, heptyl-, and decyl-) family with Cl, [BF4], and [PF6] counterions. Liquid densities, microstructures, translational diffusion coefficients, and re-orientational motion of these model ionic liquid systems have been systematically studied over a wide temperature range. The addition of neutral beads in cationic models leads to a transition of liquid morphologies from dispersed apolar beads in a polar framework to that characterized by bi-continuous sponge-like interpenetrating networks in liquid matrices. Translational diffusion coefficients of both cations and anions decrease upon lengthening of the neutral chains in the cationic models and by enlarging molecular sizes of the anionic groups. Similar features are observed in re-orientational motion and time scales of different cationic models within the studied temperature range. The comparison of the liquid properties of the ionic systems with their neutral counterparts indicates that the distinctive microstructures and dynamical quantities of the model ionic liquid systems are intrinsically related to Coulombic interactions. Finally, we compared the computational efficiencies of three linearly scaling O(NlogN) Ewald summation methods, the particle-particle particle-mesh method, the particle-mesh Ewald summation method, and the Ewald summation method based on a non-uniform fast Fourier transform technique, to calculate electrostatic interactions. Coarse-grained simulations were performed using the GALAMOST and the GROMACS packages and hardware efficiently utilizing graphics processing units on a set of extended [1-decyl-3-methylimidazolium][BF4] ionic liquid systems of up to 131072 ion pairs.

    Towards a generic compression solution for densely and sparsely sampled light field data2018In: Proceedings of 24TH IEEE International Conference On Image Processing, 2018Conference paper (Refereed)
    Abstract [en]

    Light field (LF) acquisition technologies capture the spatial and angular information present in scenes. The angular information paves the way for various post-processing applications such as scene reconstruction, refocusing, and synthetic aperture. The light field is usually captured by a single plenoptic camera or by multiple traditional cameras. The former captures a dense LF, while the latter captures a sparse LF. This paper presents a generic compression scheme that efficiently compresses both densely and sparsely sampled LFs. A plenoptic image is converted into sub-aperture images, and each sub-aperture image is interpreted as a frame of a multiview sequence. In comparison, each view of the multi-camera system is treated as a frame of a multi-view sequence. The multi-view extension of high efficiency video coding (MVHEVC) is used to encode the pseudo multi-view sequence.This paper proposes an adaptive prediction and rate allocation scheme that efficiently compresses LF data irrespective of the acquisition technology used.

    Proposed pavement markings to reduce right-turning vehicular crashes2018Conference paper (Refereed)
    Abstract [en]

    An unprotected (permitted) right-turn is when a driver is allowed to make a right turn and merge with non-stopping cross traffic stream. In this case, the turning driver will need to use his/her judgment to select a proper time gap for departure, which is not always accurate and could lead to serious right-turning vehicular crashes. This paper proposes the use of advisory pavement markings that may be painted through a certain distance upstream of intersections where drivers make unprotected right-turning departures. The proposed pavement markings are expected to aid those right-turning drivers by setting a limit for them so that the presence of any cross-traffic approaching vehicles over those pavement markings gives an indication to the turning driver that a proper time gap is not available to start departure. A methodology is presented to calculate the distance upstream of the intersection where the proposed markings should extend. The presented methodology takes into consideration the speed of the approaching vehicles as well as the acceleration profile of the departing vehicle. A two-stage acceleration profile was selected for the departing vehicle based on actual data collected where acceleration rate increases with the increase of the speed up to 20 km/h and then it starts to decrease. A design table is also provided to aid roadway designers in selecting the distance upstream of the intersection where the proposed pavement markings should be extended.

    Adaptive Video with SCReAM over LTE for Remote-Operated Working Machines2018In: Wireless Communications and Mobile ComputingArticle in journal (Refereed)
    Abstract [en]

    Remote operation is a step toward the automation of mobile working machines. Safe and efficient teleremote operation requires good-quality video feedback. Varying radio conditions make it desirable to adapt the video sending rate of cameras to make the best use of the wireless capacity. The adaptation should be able to prioritize camera feeds in different directions depending on motion, ongoing tasks, and safety concerns. Self-Clocked Rate Adaptation for Multimedia (SCReAM) provides a rate adaptation algorithm for these needs. SCReAM can control the compression used for multiple video streams using differentiating priorities and thereby provide sufficient congestion control to achieve both low latency and high video throughput. We present results from the testing of prioritized adaptation of four video streams with SCReAM over LTE and discuss how such adaptation can be useful for the teleremote operation of working machines.

    Tre domar – en studie av begränsningen av kvinnors rätt att manifestera sin religion i arbetslivet2018In: Arbetsmarknad & Arbetsliv, ISSN 1400-9692, Vol. 24, no 1-2, p. 80-97Article in journal (Refereed)
    Abstract [sv]

    I denna artikel granskas och diskuteras anställdas rätt att manifestera sin religion i arbetslivet. Studien bygger på tre domar där kvinnors rätt att bära huvudduk, respektive att vägra medverka i abortvård, ställts mot arbetsgivarens företags- och arbetsledningsrätt. Domarna analyseras utifrån teorin om normativa grundmönster där rättsreglerna sätts i relation till underliggande normer i samhället. I artikeln visas dels på de rättsliga konsekvenserna när kategorin kön tillförs, dels på paradigm i arbetslivet som handlar om assimilering. Arbetsgivare har såväl möjligheter som skyldigheter att arbeta för ett inkluderande arbetsliv. Stöd för detta finns i diskrimineringslagens bestämmelser om aktiva åtgärder.

  • Shared and paid parental leave: Nordic Information on Gender (NIKK)2018Other (Other (popular science, discussion, etc.))
    Abstract [en]

    Promoting gender equality at work is not only a matter of rights; it is the smart thing to do from the perspective of inclusive growth. The Nordic region is a case in point, as it has come to represent the 11th largest economy in the world, not despite policy commitments to gender equality and social justice, but because of it. The Nordic countries have robust economies and good living conditions, where both women and men have high labour force participation rates. However, the gender pay gap is persistent and occupational segregation continues to hinder gender equality.

    The Nordic Gender Effect at Work briefs share the collective Nordic experience in investing in gender equality including parental leave, childcare, flexible work arrangements, leadership and equal opportunities at work, and seek to make further progress through cooperation.

    I spänningsfältet mellan institutionella logiker - professionella och frivilliga vid skogsbranden i Västmanland2018In: Arbetsmarknad & Arbetsliv, ISSN 1400-9692, Vol. 24, no 1-2, p. 62-79Article in journal (Refereed)
    Abstract [sv]

    Denna artikel handlar om räddningstjänstens och frivilligas insatser och samverkan vid skogsbranden i Västmanland år 2014. Artikeln anknyter till forskning om professioner och organisering av arbete, samt till forskning om professionellas respektive frivilligas insatser och samverkan vid kriser och olyckor. En kvalitativ analys av intervjuer med räddningstjänstpersonal och frivilliga, inlägg på sociala media samt sekundärmaterial i form av rapporter och utvärderingar av räddningsinsatsen visar att insatserna vid skogsbranden i Västmanland, och kontakterna mellan professionella och frivilliga, tog form i spänningen mellan olika former av institutionella logiker: professionell logik, lokalsamhälleslogik, byråkratisk logik och marknadslogik.

    Process Optimization of UV-Based Advanced Oxidation Processes in VOC Removal Applications2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Air pollution is a major concern in developed countries due to its hazardous health effects. Recent studies by the WHO (World Health Organization) estimate that urban air pollution causes a number of diseases of the respiratory tract and is associated with 150,000 deaths each year. Volatile organic compounds (VOCs) are among the major pollutants affecting the outdoor air quality. Given that industrial processes are the main source of atmospheric VOC emissions, national and international authorities have issued regulations to limit such emissions. However, traditional removal technologies such as incineration, have low energy efficiency and high investment costs. AOPs (advanced oxidation processes) offer a promising alternative in which very reactive conditions can be achieved at room temperature, thus greatly increasing energy efficiency. However, this is still not a mature technology due to challenges that limit the range of applications.

    This thesis focuses on two types of UV-based AOP: photocatalysis and UV-ozone. The goal is to improve VOC conversion and achieve a process that is competitive with traditional technologies. The research on photocatalysis presents an innovative UV reactor design that is closer to industrial conditions and has the ability to effectively screen different samples. Effort was put into finding a metallic support for the photocatalyst without using additional adhesives. Several electrochemical treatments were performed on metals to restructure the surface. One treatment proved to be superior when it came to stabilizing the TiO2 coating, especially when compared with the traditional ceramic support.

    Research on UV-ozone AOPs focused on reactor modelling, developing a numerical and a fluid dynamics model. The goal was to gain a deep understanding of the governing phenomena of UV-ozone reactors so as to optimize the reactor configuration. The numerical model created described the UV irradiation and the reaction kinetics accurately, while a computational fluid dynamics (CFD) simulator modelled the fluid a larger scale, simulating two prototypes. The work resulted in general guidelines for the design of UV-ozone UV reactors as well as for full-scale units.

    Effect of increasing workload on knee extensor and flexor muscular activity during cycling as measured with intramuscular electromyography.2018In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, no 8, article id e0201014Article in journal (Refereed)
    Abstract [en]

    The purpose of this study was to describe the effect of increasing workload on individual thigh muscle activation during a 20 minute incremental cycling test. Intramuscular electromyographic signals were recorded from the knee extensors rectus femoris, vastus lateralis, vastus medialis and vastus intermedius and the knee flexors semimembranosus, semitendinosus, and the short and long heads of the biceps femoris during increasing workloads. Mean activation levels were compared over the whole pedaling cycle and the crank angles at which onset and offset of activation and peak activity occurred were identified for each muscle. These data were compared between three workloads. EMG activation level significantly increased (p<0.05) with increasing workload in the rectus femoris, vastus medialis, vastus lateralis, vastus intermedius, biceps femoris long head, semitendinosus and semimembranosus but not in the biceps femoris short head. A significant change in activation timing was found for the rectus femoris, vastus lateralis, vastus medialis and semitendinosus. Of the knee flexors only the short head of the biceps femoris had its peak activity during the upstroke phase at the two highest workloads indicating a unique contribution to knee flexion.

    Pedunculate Oaks (Quercus robur L.) Differing in Vitality as Reservoirs for Fungal Biodiversity2018In: Frontiers in Microbiology, ISSN 1664-302X, E-ISSN 1664-302X, Vol. 9, article id 1758Article in journal (Refereed)
    Abstract [en]

    Ecological significance of trees growing in urban and peri-urban settings is likely to increase in future land-use regimes, calling for better understanding of their role as potential reservoirs or stepping stones for associated biodiversity. We studied the diversity of fungal endophytes in woody tissues of asymptomatic even aged pedunculate oak trees, growing as amenity trees in a peri-urban setting. The trees were classified into three groups according to their phenotypic vitality (high, medium, and low). Endophytes were cultured on potato dextrose media from surface sterilized twigs and DNA sequencing was performed to reveal the taxonomic identity of the morphotypes. In xylem tissues, the frequency and diversity of endophytes was highest in oak trees showing reduced vitality. This difference was not found for bark samples, in which the endophyte infections were more frequent and communities more diverse than in xylem. In general, most taxa were shared across the samples with few morphotypes being recovered in unique samples. Leaf phenolic profiles were found to accurately classify the trees according to their phenotypic vitality. Our results confirm that xylem is more selective substrate for endophytes than bark and that endophyte assemblages in xylem are correlated to the degree of host vitality. Thus, high vitality of trees may be associated with reduced habitat quality to wood-associated endophytes.

    Search for squarks and gluinos in final states with jets and missing transverse momentum using 36  fb−1 of √s=13  TeV pp collision data with the ATLAS detector2018In: Physical Review D: covering particles, fields, gravitation, and cosmology, ISSN 2470-0010, E-ISSN 2470-0029, Vol. 97, no 11, article id 112001Article in journal (Refereed)
    Abstract [en]

    A search for the supersymmetric partners of quarks and gluons (squarks and gluinos) in final states containing hadronic jets and missing transverse momentum, but no electrons or muons, is presented. The data used in this search were recorded in 2015 and 2016 by the ATLAS experiment in root s = 13 TeV proton-proton collisions at the Large Hadron Collider, corresponding to an integrated luminosity of 36.1 fb(-1). The results are interpreted in the context of various models where squarks and gluinos are pair produced and the neutralino is the lightest supersymmetric particle. An exclusion limit at the 95% confidence level on the mass of the gluino is set at 2.03 TeV for a simplified model incorporating only a gluino and the lightest neutralino, assuming the lightest neutralino is massless. For a simplified model involving the strong production of mass-degenerate first-and second-generation squarks, squark masses below 1.55 TeVare excluded if the lightest neutralino is massless. These limits substantially extend the region of supersymmetric parameter space previously excluded by searches with the ATLAS detector.

    Identifying and assessing the potential hydrological function of past artificial forest drainage2018In: Ambio, ISSN 0044-7447, E-ISSN 1654-7209, Vol. 47, no 5, p. 546-556Article in journal (Refereed)
    Abstract [en]

    Drainage of forested wetlands for increased timber production has profoundly altered the hydrology and water quality of their downstream waterways. Some ditches need network maintenance (DNM), but potential positive effects on tree productivity must be balanced against environmental impacts. Currently, no clear guidelines exist for DNM that strike this balance. Our study helps begin to prioritise DNM by: (1) quantifying ditches by soil type in the 68 km(2) Krycklan Catchment Study in northern Sweden and (2) using upslope catchment area algorithms on new high-resolution digital elevation models to determine their likelihood to drain water. Ditches nearly doubled the size of the stream network (178-327 km) and 17% of ditches occurred on well-draining sedimentary soils, presumably making DNM unwarranted. Modelling results suggest that 25-50% of ditches may never support flow. With new laser scanning technology, simple mapping and modelling methods can locate ditches and model their function, facilitating efforts to balance DNM with environmental impacts.

    Sustainability Leaders’ Perceptions on the Drivers for and the Barriers to the Integration of Sustainability in Latin American Higher Education Institutions2018In: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 10, no 8, article id 2954Article in journal (Refereed)
    Abstract [en]

    Higher education institutions (HEIs) have been steadily progressing towards the integrationof sustainable practices in their structures and operations. Several studies have reported the varietyof drivers of change and the barriers to change that universities have found in the integrationprocess. The present investigation is aimed at further characterizing and ranking the drivers for,and barriers of, sustainability integration in HEIs within their structures and operating functions.Open-ended expert opinion interviews of key sustainability leaders appointed at 45 HEIs from10 Latin-American countries were conducted in order to learn lessons from their diverse experiencesof the process. Additionally, a thematic workshop on HEI sustainability was organized to facilitatefurther discussions between 23 sustainability scholars and/or national coordinators of universitynetworks from 11 Latin American countries. As a result, 15 barriers were identified as hinderingthe institutionalization of sustainability in HEIs. This study also examined the relationship betweenthese reported barriers with 13 main drivers that were identified to be facilitating the integration ofsustainable practices within the organizational and academic structures at the universities. The strongcorrespondence between the several observed drivers for, and barriers to, change highlights theimportance of strategic planning that offers integrated actions. The findings of this paper can serveas a reference to assist HEIs in identifying drivers of, and barriers to, sustainability, so that the formercan be fostered and the latter addressed effectively. This can help identify and plan targeted actionsto make the transition towards sustainability in HEIs more natural and effective.

    Quality of end-of-life care in patients with dementia compared to patients with cancer: A population-based register study2018In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, no 7, article id e0201051Article in journal (Refereed)
    Abstract [en]

    Introduction Globally, dementia is one of the leading causes of death. Given the growing elderly population in the world, the yearly number of deaths by dementia is expected to increase. Patients dying from dementia are reported to suffer from a burden of symptoms similar to that of patients with cancer, but receive less medication against symptoms, have a lower probability of palliative care planning and seldom have access to specialised palliative care. Studies investigating the quality of palliative care in dementia are scarce. The aim of this Swedish national study was to compare the quality of end-of-life care between patients with dementia and patients with cancer regardless of place of care. Methods Thirteen end-of-life care quality indicators collected by the Swedish Register of Palliative Care (SRPC) were compared between patients dying from dementia and patients dying from cancer. Data were collected from deaths occurring in nursing homes, hospitals, specialised and general palliative home care, and palliative in-patient units during a three-year period (during March 2012 to February 2015). Analyses were performed using a multivariable logistic regression model, adjusted for age and gender. A subgroup of patients with Alzheimer's disease was identified and compared to patients with other and unspecified types of dementia. Results A total of 4624 deaths from Alzheimer's disease, 11 804deaths from other dementia diagnoses and 51 609 deaths from cancer were included. For six of the 13 quality indicators examined (prescription of PRN drugs against nausea and anxiety, information and bereavement support offered to next of kin, pain assessment and specialised palliative care consultations), poorer outcomes were shown for the dementia group in comparison to the cancer group. Two outcomes (prevalence of pressure ulcers and fluid therapy during the last 24 hours in life) showed better outcomes for the dementia group. The outcomes for the 13 quality indicators were similar for patients with Alzheimer's disease compared to patients with other and unspecified types of dementia. Conclusions The findings in this study indicates that patients dying from Alzheimer's disease and other types of dementia receive a poorer quality of end-of-life care concerning several important end-of-life care areas when compared to patients dying from cancer. Guidelines for end-of-life care in Sweden cannot explain or justify these differences. Further studies are needed to find possible ways to improve end-of-life care in the large and growing group of patients dying from dementia.

    A health coaching self-management programme for patients with Chronic Obstructive Pulmonary Disease: An explorative and interventional study2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background: Chronic Obstructive Pulmonary Disease (COPD) is a primary cause of chronic morbidity and mortality and contributes to an increased economic and social burden on patients and families. Self-management education as one non-pharmacological treatment approach is highlighted in guidelines. Although self-management programmes have shown positive effects for COPD, lack of disease-specific self-management skills, high dropout rates, and poor attendance of participants are problems which should be taken under consideration. One way to cope with the problems is to use amore motivational approach which focuses on patients’ health decisions in cooperation with healthcare practitioners, combined with systematic and structured health coaching. However, there is a lack of such studies, which are needed to explore the effects of self-management on patients with COPD by health coaching, not least in China.

    Aims: The overall aim of this thesis was to explore sociodemographic and clinical factors influencing self-management and to test and evaluate a health coaching self-management programme for patients with COPD in China.

    Methods: The study’s design was explorative, prospective, and longitudinal, with both quantitative and qualitative approaches. Specifically, a quantitative method with a cross-sectional approach was used to explore the self-management status of patients with COPD and examine the associations with socio-demographic and clinical variables (I). Furthermore, a prospective randomized controlled trial was conducted to study the longitudinal effects of the health coaching self-management programme using a repeated-measures analysis of variance model of patients with COPD (II & III). A qualitative study implementing inductive content analysis was used to describe and explore participants’ experiences of the health coaching self-management programme of patients with COPD (IV).

    Results: High physical activity, high salary, and low age affected the self-management of patients with COPD most positively (I). The health coaching programme improved lung function, physical activity, quality of life, and self-management skills, as well as psychological status in both the short and long term (II & III). Participants expressed their experiences of the health coaching self-management programme as making them more aware of the importance of knowledge of the disease and their own responsibilities, taking action to maintain a healthy lifestyle, feeling supported by the programme, and being hindered by individual and programme limitations (IV).

    Conclusions: This thesis contributes to knowledge about the self-management skills of patients with COPD, which is low in China. A health coaching self-management programme with iterative interactions between patients and healthcare professionals represented a valuable and effective intervention designed to improve health-related outcomes. Moreover, low literacy, poor physical condition, and family and economic burdens should be taken into account in the development of future self-management programmes in China.
