Background and Objective: This narrative review addresses idiopathic acute pancreatitis (IAP) and its epidemiology, diagnosis, clinical course and treatment during the last decade. As there is no previously validated protocol for finding the aetiology of acute pancreatitis (AP), the primary aim of this study is to find, describe and unify evidence about the diagnostic work-up of AP to diagnose the
Treating severe dermal disruptions often presents significant challenges. Recent advancements have explored biological cell sprays as a promising treatment, but their success hinges on efficient cell delivery and complete wound coverage. This requires a good spray distribution with a small droplet size, high particle number, and ample surface coverage. The type of nozzle used with the spray device
A search has been performed, using the full 20.3 fb(-1) data sample of 8 TeV proton-proton collisions collected in 2012 with the ATLAS detector at the LHC, for photons originating from a displaced vertex due to the decay of a neutral long-lived particle into a photon and an invisible particle. The analysis investigates the diphoton plus missing transverse momentum final state, and is therefore mos

A combination of qualitative and quantitative methods was use i.e. open-ended inte
Objective: Valid dietary data are essential when trying to identify whether or not one or more dietary exposures are responsible for disease. We examined diet composition in women who reported dietary change in the past compared with non-changers, and how the associations between dietary factors and postmenopausal breast cancer are influenced by dietary change, obesity status and misreporting of e
For construction in rock a thorough pre-investigation is important in order to avoid unforeseen conditions which may delay the work. It is crucial to remember the results from this investigation in the further work, and use the experience from the construction to update the geological prognosis and reduce the uncertainties. Different geophysical methods have proved valuable tools in such investiga
Amplitudes, rates, periodicities, causes and future trends of temperature variations based on tree rings for the past 2485 years on the central-eastern Tibetan Plateau were analyzed. The results showed that extreme climatic events on the Plateau, such as the Medieval Warm Period, Little Ice Age and 20th Century Warming appeared synchronously with those in other places worldwide. The largest amplit
Background: In preparing the fifth edition of the Nordic Nutrition Recommendations (NNR), the scientific basis of specific food-based dietary guidelines (FBDG) was evaluated. Objective: A systematic review (SR) was conducted to update the NNR evidence based on the association between the consumption of potatoes, berries, whole grains, milk and milk products, and red and processed meat, and the ris
Abstrakt Self-harming patients is a problem nurses’ faces in their everyday work. In Sweden approximately 7800 people is hospitalised due to self-harm. The aim of this study is to examine what factors influences nurses’ attitudes and care towards patient who self-harm.

Under hösten 2016 utlystes en sluten arkitekttävling om ett nytt kulturhus Bergsjön. Bergsjön är en stadsdel i utkanten av nord-östra Göteborg. Många upplever området som isolerat från resten staden både fysiskt och socialt. Bebyggelsen, som i stort sett är helt intakt från 60-och 70-talet, speglar de dåvarande idealen och bjuder på såväl möjligheter som utmaningar. Samtidigt ligger stadsdelen i mDuring the fall in 2016 the city of Gothenburg announced a competition for a new house of culture located in Bergsjön. Bergsjön is a district in the north east part of the city. A lot of people view the area as isolated from the rest of the city, both physically and socially. The near intact development from the 60s and 70s, reflect the ideals of the time which means both great possibilities and c
Research indicates a crisis in the journalistic field due to economic, technological, institutional and cultural shifts. This seems to have led to a paradigm shift in arts journalism, from a cultural to a journalistic focus, and a loss of autonomy for culture departments in the Swedish press. This article investigates how arts journalists’ professional values are affected by this presumed autonomy
Growing amounts of waste generation in remote areas without proper waste management systems is a problem to human health and the environment. The Amazon holds the biggest freshwater resources in the world, is a biodiversity hotspot and its communities are placed in distances that can take days by boat to be reached. A National policy with EPR instruments requires private companies to take-back pac
