Background: Fracture displacement is the most important factor associated with nonunion of a scaphoid waist fracture. We evaluated the performance characteristics of radiographs and computed tomography (CT) in the diagnosis of intraoperative displacement and instability of scaphoid waist fractures using wrist arthroscopy as the reference standard. Methods: During a six-year period (2004 to 2010) a

Introduction: In sepsis, mitochondria have been associated with both initial dysfunction and subsequent upregulation (biogenesis). However, the evolvement of mitochondrial function in sepsis over time is largely unknown, and we therefore investigated mitochondrial respiration in peripheral blood immune cells (PBICs) in sepsis patients during the first week after admission to the intensive care uni

This article analyses and discusses standardisation in human service organisations and its implications for professionals and for professionalism in social work. The theoretical framework derives from neo-institutional theory and theories regarding professionalism. By highlighting the role of professionals within a field influenced by organisational demands and market endeavour, this article contr

Various differential cross-sections are measured in top-quark pair (t (t) over bar) events produced in proton-proton collisions at a centre-of-mass energy of root s = 7 TeV at the LHC with the ATLAS detector. These differential cross-sections are presented in a data set corresponding to an integrated luminosity of 4.6 fb(-1). The differential cross-sections are presented in terms of kinematic vari

Background: The preclinical patterns of biological markers for Alzheimer's disease (AD) in vivo need further exploration. The aim of this study was therefore to investigate CSF biomarkers, regional cerebral blood flow (rCBF) and cognitive performance in cognitively healthy older individuals. Method: Within a 2-week period, 32 cognitively healthy older individuals underwent CSF analysis, rCBF m

To investigate biomarker patterns in rheumatoid arthritis (RA) with extraarticular manifestations.

Background: Photoallergic contact dermatitis (PACD) is an uncommon condition, and there is a lack of validated criteria for its diagnosis. Objective: To identify a set of relevant criteria to be considered when suspecting a diagnosis of PACD and to assess the reproducibility of these criteria. Methods: This was a diagnostic item selection and reliability study performed between July 2012 and Octob

Background There are limited data comparing radiofrequency catheter ablation with antiarrhythmic drug therapy as first-line treatment in patients with paroxysmal atrial fibrillation. Methods We randomly assigned 294 patients with paroxysmal atrial fibrillation and no history of antiarrhythmic drug use to an initial treatment strategy of either radiofrequency catheter ablation (146 patients) or the

We investigated neural distinctions between inflectional and derivational morphology and their interaction with lexical frequency using the mismatch negativity (MMN), an established neurophysiological index of experience-dependent linguistic memory traces and automatic syntactic processing. We presented our electroencephalography (EEG) study participants with derived and inflected words of variabl

Sterically hindered amines, such as 2-amino-2-methyl-1-propanol (AMP), are an interesting alternative to the amines used in conventional CO2 absorption processes in industrial applications. One reason for this is because the carbamate formed is not stable, which may be beneficial during the regeneration of the amine solution in terms of a reduced energy requirement. This paper presents experiment

We demonstrate that the crystal structure of InAs nanowires call be controlled with nanowire diameter and growth temperature. At small diameters, the nanowires exhibit a wurtzite Structure. As the diameter is increased, there is a crossover to the zinc blende structure. The crossover is less sharp at lower growth temperature and L, the crossover diameter decreases as the growth temperature is incr

BACKGROUND: A novel way to evaluate muscle strength and functioning in the lower limbs is to measure how high a person could step up on a platform, the so called Maximal Step-up Test (MST). Studies of healthy persons and overweight women have shown that the maximal step-up height (MSH) is associated with both muscle strength and physical function, but no study has assessed persons after stroke. OB

Exposure, sensitivity and adaptive capacity are essential, albeit theoretically vague, components of climate vulnerability. This has triggered debate surrounding how these factors can be translated into, and understood in, an empirical context subject to present and future harm. In this article, which draws on extensive fieldwork in the Lake Victoria Basin of Kenya and Tanzania, we illustrate how

Background: It is known that some patch-test preparations containing disperse dyes contain impurities with unknown relevance for the development or elicitation of contact allergy. Objective: To evaluate the significance of the impurities found in the commercial dyes Disperse Orange 1 (DO1) and Disperse Yellow 3 (DY3) regarding contact allergy in patients with known sensitivity to them. Metho

Background: Patch testing has been used for more than 100 years as the best means to diagnose contact allergy. The increased use of the technique makes standardization of the methodology most important. Progress in the standardization of the patch test technique has been made through guidelines. Objectives: To investigate the intra-individual and inter-individual differences in reading of patch
