Introduction: Hip fractures are commonly diagnosed by plain radiography. When a patient presents with negative radiographs and high clinical suspicion of fracture, guidelines recommend proceeding with magnetic resonance imaging (MRI) to diagnose the patient. The aim of this study was to assess the use of MRI in diagnosing hip fractures following trauma to the hip and describe clinical outcome afte
Background. Poor ultrafiltration is associated with worse outcomes in peritoneal dialysis (PD) patients. This might in part reflect problems associated with salt and water excess. Increasing the diffusive component of peritoneal sodium removal using low-sodium PD fluids might have beneficial effects on blood pressure (BP), thirst and fluid status that could translate into clinical benefits. Method
Background. The optimal care for patients with unresectable, non-metastatic pancreatic adenocarcinoma (PAC) is debated. We treated 17 consecutive cases with preoperative radiochemotherapy (RCT) as a means for downstaging their tumours and compared outcome with 35 patients undergoing direct surgery for primarily resectable PAC during the same time period. Methods. The patients had biopsy proven, un
Objective: Advanced glycation end products (AGE) have been implicated in diabetic vascular complications through activation of pro-inflammatory genes. AGE-modified proteins are also targeted by the immune system resulting in the generation of AGE-specific autoantibodies, but the association of these immune responses with diabetic vasculopathy remains to be fully elucidated. The aim of this study w
A Summary In a large cohort of elderly women followed for 10 years, we found that balance, gait speed, and self-reported history of fall independently predicted fracture. These clinical risk factors are easily evaluated and therefore advantageous in a clinical setting. They would improve fracture risk assessment and thereby also fracture prevention. Introduction The aim of this study was to identi
For historical reasons, Swedish railways use 15 kV/16? Hz overhead contact lines for train traction, while the most common standard worldwide is 25 kV/50-60 Hz. This leads to higher investment costs for railway conversions and expansions, and to greater energy losses in the distribution of electricity to the trains. Yet to get away from these drawbacks by investing in a 25 kV/50 Hz overhead contac
Understanding and being able to quantify sitting postures is a central asset in car safety evaluations. This is due to the fact that passengers can choose a range of different sitting positions. Studying and understanding how passengers choose to sit to obtain some comfort is important for increased safety in futures cars and is particularly challenging facing a heterogeneous population. Data is a
Popular science summary Has climate change influenced flowering time of coltsfoot? Phenological events such as the onset of flowering during the spring are among the most sensitive indicators of climate change. Hence, phenological data have recently emerged as effective tools for studying the impact of climate change on species and ecosystems. In this study, I used records from herbaria and pub
Copper and copper alloys are important material systems for the electrification of society. The high workability of the materials makes them appropriate in numerous different applications which require highly conductive properties. One main advantage of Cu and Cu-bearing alloys is the eminent ability to be repeatedly recycled without losing the advantageous properties. This raises the question whe
Sharenting är ett relativt nytt fenomen som fått stor medial uppmärksamhet de senaste åren. Vårdnadshavare i form av privatpersoner och influensers tenderar att obetänksamt dela bilder och information om sina barn på nätet utan att tänka på vilka konsekvenser delandet kan leda till. Barns rättigheter har stärkts i allmänhet när FN:s Barnkonvention inkorporerades i svensk lagstiftning år 2020. BarnSharenting is a relatively new phenomenon which has received a great deal of media attention in recent years. Guardians in the form of private individuals and influencers tend to carelessly share photos and information about their children online without thinking about the consequences of sharing. Children's rights have been strengthened in general when the UN Convention on the Rights of the C
Highly adhesive glycoprotein von Willebrand factor (VWF) multimer induces platelet aggregation and leukocyte tethering or extravasation on the injured vascular wall, contributing to microvascular plugging and inflammation in brain ischemia-reperfusion. A disintegrin and metalloproteinase with thrombospondin type-1 motifs 13 (ADAMTS13) cleaves the VWF multimer strand and reduces its prothrombotic a
BACKGROUND: Open abdomen (OA) therapy frequently results in a giant planned ventral hernia. Vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) enables delayed primary fascial closure in most patients, even after prolonged OA treatment. Our aim was to study the incidence of hernia and abdominal wall discomfort 1 year after abdominal closure. METHODS: A prospective multicenter
BACKGROUND: The NOCTET (NOrdic Certican Trial in HEart and lung Transplantation) trial demonstrated that everolimus improves renal function in maintenance thoracic transplant (FIX) recipients. Nevertheless, introduction of everolimus is not recommended for patients with advanced renal failure. We evaluated NOCTET data to assess everolimus introduction amongst TTx recipients with advanced renal fai
Guðrún Guðjónsdóttir Climate change is having a great impact on the fragile High Latitude environment where warming is occurring at a rate at least double the global average. It is urgent to understand the relationship between climate and vegetation cover, which is playing an important role, as a carbon sink, for biodiversity, and for protecting against natural hazards. Less studied but equally i

Studien har utförts som en kombination av kvalitativa och kvantitativa forskningsmetoder, vilket kan liknas vid begreppet triaThe purpose of the study is to come up with recommendations and advice on how to calculate and present the climate impact from construction works. This will be implemented by examining how other actors within the construction industry is acting on the issue and examine models and tools for climate calculations. The study was conducted as a combination of qualitative and quantitative research meth
Skattelagstiftning styrs av principer, som ibland kan säga emot varandra och då behöva vägas mot varandra. I förarbeten redogör lagstiftaren för hur denna bedömning ser ut, och det är möjligt att genom förarbeten analysera vilka principer lagstiftaren behandlar, hur de behandlas och hur de vägs mot varandra. Det finns olika sätt att dela in skatterättsliga principer; ett sätt är att dela in dem i Tax law is governed by principles, that sometimes may contradict each other and then need to be weighed against each other. In preparatory works the lawmaker gives their account for how the assessment of principles looks like, and it’s possible through preparatory works to analyse which principles the lawmaker considers, how they’re considered, and how they’re weighed against each other. There are
Biomanipulation, i.e. to reduced planktivorous- and benthivorous fish in order to receive changes in the trophic structure has been a successful method to improve water quality and the ecological status in eutrophic lakes. The initial idea was to increase the abundance of large zooplankton and thus to cause a trophic cascade with reduced algal biomass. Many studies failed to observe an increase of
Ovako Ajax me, in York, South Carolina, USA manufactures seamless steel rings. The rings are made from blocks, which are heated, pressed, punched and then rolled to desired size and shape. Due to tougher competition on the seamless steel ring market, it is necessary to know the total production time for an order of specific rings, in order to be able to price the rings correctly and plan the prod
Structural and mechanical alterations during hypertrophy of the rat portal vein were investigated. Growth of the vessel was induced by a partial ligature of the vessel causing an increased transmural pressure. Vessel segments from animals kept with ligature for 1, 3, 5 and 7 days, were compared with vessels from sham-operated animals. Maximal active force and vessel cross-sectional area increased
