Background: There is compelling evidence showing that achieving good glycaemic control reduces the risk of microvascular complications in people with type 1 and type 2 diabetes. Likewise, there is clear evidence to show that achieving good glycaemic control reduces the risk of macrovascular complications in type 1 diabetes. The UKPDS 10-year follow up suggests that good glycaemic control also redu

I klinisk praxis görs palpation per rektum rutinmässigt på vuxna patienter vid akut buk. Vi utvärderade evidensen för detta genom en systematisk litteratursökning och identifierade 16 relevanta originalstudier. Dessa visade att det saknas evidens för diagnostisk nytta av rektalpalpation vid akut buk, inklusive misstänkt appendicit. Rutinmässig rektalpalpation bör inte göras vid akut buk hos vuxnaA digital rectal examination (DRE) is standard practice in cases of acute abdomen in adult patients. We analyzed the evidence for this by a systematic literature search, and identified 16 relevant original studies. These studies showed that there is no evidence for a diagnostic value of DRE in adult patients with acute abdomen. We should stop doing routine DRE in adult cases of acute abdomen.

Free space optics is an interesting alternative for telemetry with medical implants, due to the high data bandwidths available at optical frequencies. Especially implanted brain-computer interfaces gives rise to large data sets that needs to be transmitted transcutaneous. In this paper we show that it is possible to establish such a link at near-IR wavelengths using a modulated reflector in the im

Popular Abstract in Swedish Bakgrund Man kan fråga sig varför en hel avhandling handlar om något så ovanligt som akut mastoiditit hos barn. Det är den vanligaste komplikationen till öroninflammation men drabbar bara 20-60 barn per år i Sverige. Öroninflammation däremot är en infektion som är så vanlig att nästan alla har haft åtminstone en sådan som barn. I Sverige diagnostiseras upp emot 200 000 One of the greatest threats to society today is the development of bacterial resistance to antibiotics. It is commonly accepted that this is mainly due to the use of antibiotics. Acute otitis media (AOM) is responsible for the highest number of antibiotic prescriptions to children although it is in most cases a self-limiting disease. Nevertheless, complications do occur in some case and the most c

In this paper, we propose a method for estimating statistical periodicities in symbolic sequences. Different from other common approaches used for the estimation of periodicities of sequences of arbitrary, finite, symbol sets, that often map the symbolic sequence to a numerical representation, we here exploit a likelihood-based formulation in a sparse modeling framework to represent the periodic b

A rectangular, straight microchannel heat sink with multiple length bifurcation has been designed, and the corresponding laminar flow and thermal performance have been investigated, numerically. Five different cases with multiple length bifurcation and various arrangements are investigated, as well as one case without bifurcations. All laminar fluid flow and surface heat transfer results are obtai

A series of comparative studies is suggested, focused on perceptions of outrigger canoes, and aimed at an increased understanding of the relationship between social relations, biodiversity, and sustainable development in Oceanic societies on small islands and in coastal areas undergoing rapid cultural change. After a critique of the recent notion that canoe-building in Polynesia developed as a res

Inclusive transverse momentum spectra of primary charged particles in Pb-Pb collisions at root s(NN) = 2.76 TeV have been measured by the ALICE Collaboration at the LHC. The data are presented for central and peripheral collisions, corresponding to 0-5% and 70-80% of the hadronic Pb-Pb cross section. The measured charged particle spectra in |eta| < 0.8 and 0.3 < p(T) < 20 GeV/c are compared to the

Björn Lindman has for fifty years had an active role in science and technology. His main contributions are briefly described. In the science part particular emphasis is put on his studies of ion binding, of amphiliphilc self-association, of molecular diffusion in solution and of polymer-surfactant systems. Furthermore we describe his role in introducing scientific areas, his role in scientific col

Abstract Levels of natural radioactivity such as 222Rn (radon) and its long-lived daughters 210Pb and 210Po were measured. The radon gas was trapped on cooled charcoal filters and the long-lived daughter products sampled on fibre filters on a daily basis. In addition, short-lived progenies were followed continuously on the filters in order to achieve a time resolution of about one hour. The ave

A search for neutral Higgs bosons decaying to pairs of tau leptons with the ATLAS detector at the LHC is presented. The analysis is based on proton-proton collisions at a center-of-mass energy of 7 TeV, recorded in 2010 and corresponding to an integrated luminosity of 36 pb(-1). After signal selection, 276 events are observed in this data sample. The observed number of events is consistent with th

We demonstrate a vertical InAs nanowire MOSFET integrated on Si substrate with an extrinsic peak cut-off frequency of 103 GHz and a maximum oscillation frequency of 155 GHz. The transistor has a transconductance of 730 mS/mm and is based on arrays of nanowires with gate-all-around and high-kappa gate dielectric. Furthermore, small-signal modeling shows a similar to 80% reduction of the total paras

Objective. To construct a database for clinical epidemiological prostate cancer research based on linkages between the National Prostate Cancer Register (NPCR) of Sweden, a population-based, nationwide quality database, and other nationwide registries. Material and methods. By use of the individually unique Swedish Personal Identity Number, the NPCR was linked to the Swedish Cancer Registry, the C

Popular Abstract in Swedish Barn födda före 32 gestationsveckor, även de utan svåra neurologiska avvikelser, har en hög förekomst av neuropsykologiska problem såsom läs-, inlärnings-, språk-, minnes- och beteendeproblem. Det är ännu inte klarlagt vilka funktionella och strukturella förändringar i hjärnan som orsakar dessa problem. Möjligheten till tidig diagnos behövs men saknas ännu. Auditiva hänChildren born before 32 gestational weeks have a high incidence of neuropsychological deficits. The structural and functional correlates of such impairments in preterm infants are incompletely understood, and early diagnostic tools are needed, but still lacking. Auditory event-related potentials (AERPs) are neurophysiological measures of cortical sound detection, encoding, discrimination, and atte

This paper looks at the notion of the body as an interior landscape that is made intelligible through visual representation. It discerns the key figure of the inner corporeal voyage, identifies its main elements and examines how contemporary artists working with performances and installations deal with it. A further aim with the paper is to discuss what kind of image of the body that is conveyed t

We study the effects of NaCl on the self-assembly of AAKLVFF and beta A beta AKLVFF in solution. Both AAKLVFF and beta A beta AKLVFF self-assemble into twisted fibers in aqueous solution. The addition of NaCl to aqueous solutions of AAKLVFF produces large crystal-like nanotapes which eventually precipitate. In contrast, highly twisted fibrils were observed for beta A beta AKLVFF solutions at low s

Ljusforskning är om något diversifierad och omfattar teorier och metoder från skilda discipliner som teknik, medicin och samhällsvetenskap. Det finns också en förväntan att erhållna forskningsresultat skall kunna appliceras direkt i verkliga miljöer. I och med introduktionen av LED har många tidigare studier som behandlat glödlampor, lysrör och andra ljuskällor inaktualiserats. Ny kunskap - och nyLighting research is diversified and includes theory and methodology from disciplines as different as technology, medicine and social sciences. There is also an expectation on research results to be directly applicable in real environments. The introduction of LED has furthermore made previous research on incandescent lamps, fluorescent lamps and other light sources, outdated. New knowledge – and

Popular Abstract in Swedish Våra celler är täckta av kolhydrater (socker) som är kopplade till proteiner och lipider på cellens yta. Olika celler presenterar olika socker, och en och samma cell kan dessutom ändra sitt sockeruttryck beroende på hur den mår och vad den vill utföra, till exempel dela sig eller dö, en effekt man ofta ser i cancer. På så sätt fungerar sockerstrukturerna som en kod som There is an intensive interest in characterising the structure and function of galectins, which is not surprising given their many important cellular functions and strong implications in human disease. Understanding the mechanisms involved in galectin functions will help to find selective and novel strategies for disease treatment and diagnosis. A key to this lies in their carbohydrate binding spe
