Two-dimensional (2D) topological insulators have fascinating physical properties which are promising for applications within spintronics. In order to realize spintronic devices working at room temperature, materials with a large nontrivial gap are needed. Bismuthene, a 2D layer of Bi atoms in a honeycomb structure, has recently attracted strong attention because of its record-large nontrivial gap,
Background: The aims of this study are to 1) determine the scope of musculoskeletal (MSK)-related clinical research in Sweden; 2) collate the amount of first-tier funding received; 3) discuss strategies and infrastructure supporting future MSK clinical trials in Sweden. Methods: A systematic scoping review protocol was applied in PubMed, Scopus, and SweCRIS databases. The articles were examined, a
Importance: Although tramadol is increasingly used to manage chronic noncancer pain, few safety studies have compared it with other opioids. Objective: To assess the associations of tramadol, compared with codeine, with mortality and other adverse clinical outcomes as used in outpatient settings. Design, Setting, and Participants: Retrospective, population-based, propensity score-matched cohort st
PURPOSE/OBJECTIVE(S): Studies of electron FLASH radiotherapy (FLASH-RT) in companion animals are being conducted at several institutions. High energy electron beams are generally suitable for treatment of superficial cancers, but of limited use for deep-seated tumors. In this case report, the feasibility of intracavitary electron FLASH-RT is demonstrated.MATERIALS/METHODS: A canine cancer patient
Background: Colorectal cancer screening programmes and uptake vary substantially across Europe. We aimed to compare changes over time in colorectal cancer incidence, mortality, and stage distribution in relation to colorectal cancer screening implementation in European countries. Methods: Data from nearly 3·1 million patients with colorectal cancer diagnosed from 2000 onwards (up to 2016 for most
The possibility of a “death from above” cause for biotic crises and extinction events is intriguing, to say the least, but such claims must be supported by reliable and reproducible data, not only impact diagnostic criteria, but also accurate and precise radioisotopic ages of the impact structures/events. To date, only one example of such an impact-related global extinction event is confirmed, at
Background: Many persons with late effects of polio (LEoP) perceive walking limitations in everyday life. A common rating scale to assess walking limitations is the Walking Impact Scale (Walk-12). However, there is limited knowledge about its psychometric properties. Objective: To investigate the psychometric properties of Walk-12 in persons with LEoP. Design: Rasch model analysis of cross-section
Families often prefer home care to hospital care, and home-care services for ill children are increasing worldwide with limited knowledge of families’ needs during curative and palliative home care. The aim of this study was to elucidate family members’ lived experience when a sick child received home care from county-based primary healthcare services. A descriptive qualitative design was chosen a
Background and Objectives: There is considerable heterogeneity in the association between increasing β-amyloid (Aβ) pathology and early cognitive dysfunction in preclinical Alzheimer disease (AD). At this stage, some individuals show no signs of cognitive dysfunction, while others show clear signs of decline. The factors explaining this heterogeneity are particularly important for understanding pr
Popular Abstract in English In our current world, the exponential growth in demand for smaller and faster devices leads to the fact that we will eventually face the problem that traditional semiconductor technologies will reach their limitation in terms of size and speed. Humanity's consciousness to tackle the global ecological issues in the next decade, will demand the substitution of all non-reuThe work presented in this thesis addresses the investigation of the electronic, magnetic, and structural properties of late transition metal complexes supported on various surfaces. The research is aimed at studying the interaction between the molecules and the support, together with the intermolecular interaction. This knowledge is essential e.g. for the development of organic molecule-based dev
Sperm DNA fragmentation index (DFI) assessed by sperm chromatin structure assay is a valuable tool for prediction of fertility in vivo. Previous studies on DFI as predictor of in vitro fertilization (IVF) outcome, based on relatively small materials, gave contradictory results. The present study examines, in a large cohort, the association between sperm DFI and the outcome of IVF/ICSI procedure. T
Retinitis pigmentosa is a group of inherited retinal degenerative diseases characterized by the loss of photoreceptors and vision for which no effective treatment is available. Several animal models of retinitis pigmentosa are used to elucidate its pathogenesis and to devise therapies. The retinal degeneration (rd1) mouse is one such animal model in which rod-specific phosphodiesterase (PDE) is in
Much scientific evidence indicates that the Earth's climate is changing and the world has become more concerned about the global climate. This has encouraged many countries to consider future clean power production with wind power taking an increasing part. In Sweden, the government declared the intention of generating 30 TWh/year from the wind by 2020 instead of 7.1 TWh/year achieved in 2012. Egy
Purpose: Predicting the visual gain from cataract surgery when the main cause of vision loss is age-related macular degeneration may be difficult and warrants the need for an objective predictor of subjective outcome. Full-field electroretinography is an objective measure of overall retinal function. We therefore wanted to study if full-field electroretinography can predict subjective visual outco
Aims/hypothesis: The risk of complications and medical consequences of type 2 diabetes are well known. Hospital costs have been identified as a key driver of total costs in studies of the economic burden of type 2 diabetes. Less evidence has been generated on the impact of individual diabetic complications on the overall societal burden. The objective of this study was to analyse costs of hospital
Om inte statusen på Sveriges byggnadsbestånd förbättras kommer miljömålet ”God bebyggd miljö” inte kunna uppfyllas. Då miljömålet beaktar många aspekter måste ett holistiskt synsätt gälla vid genomförandet av åtgärder i byggnadsbeståndet. För att kunna göra detta måste en dialog föras kring viktiga aspekter på byggnadens samtliga områden mellan inblandade parter. Om en parameter ändras riskerar deCurrently, Sweden faces a major environmental challenge. If the status of its building stock doesn’t improve, the environmental goal “En god bebyggd miljö” will not be reached. Since this goal considers a wide range of aspects it’s essential that the same holistic approach is considered when implementing measures on the building stock. For this to be possible, an extensive dialogue needs to be hel
För var dag som går blir vårt samhälle allt mer beroende av teknik och snabb och lättillgänglig information. De flesta av oss söker dagligen efter någon sorts information på internet. Vi gör sökningar på allt som är av intresse för oss för stunden och allt fler inköp görs numera på nätet. Med denna nya, teknikberoende livsstil har det blivit allt viktigare för företag att marknadsföra sina varor oFor each day that passes our society becomes more and more dependent on technology and a fast and easy access to information. Most of us are using internet on a daily basis in search of information. We search for information regarding most things in our lives, from health, lifestyle and food to information regarding travel and work-related issues. With this new, technology-dependent lifestyle it h
I denna scoping review har syftet varit att söka efter forskning kring vilket behov föräldrar har av stöd för att kunna prata om sexualitet med sina barn som har funktionsnedsättning och om det finns beprövad intervention. Totalt nio artiklar har granskats som har innefattat barn med autismspektrumtillstånd (AST), intellektuell funktionsnedsättning (IF) och rörelsenedsättning (RH). Resultatet visa
In order to study and evaluate the care provided at the Intensive Care Unit (ICU), an accurate model to assess severity of illness and predict patient mortality based on admission data is required. Since 1983, the Simplified Acute Physiology Score (SAPS) based on logistic regression (LR) has become one of the international standards for this purpose and is used in Sweden for adults. While being a
