Infliximab as rescue therapy in hospitalised patients with steroid-refractory acute ulcerative colitis: a long-term follow-up of 211 Swedish patients

BackgroundRescue therapy with infliximab (IFX) has been proven effective in a steroid-refractory attack of ulcerative colitis (UC). The long-term efficacy is not well described. AimTo present a retrospective study of IFX as rescue therapy in UC. Primary end points were colectomy-free survival at 3 and 12months. MethodsIn this multicentre study, 211 adult patients hospitalised between 1999 and 2010

Surveillance and File-Sharing: Two Issues Engaging the Unengaged

Abstract in UndeterminedOver the last decade a great deal of research attention has been paid to the Internet as a potential vehicle for civic and/or political engagement among young people. Many of these analyses have been looking (or perhaps hoping) for a simple cause-and-effect relationship. Young people seem uninterested in traditional forms of politics, but they are very interested in Interne

The duration of trade revisited. Continuous-time versus discrete-time hazards

The recent literature on the duration of trade has predominantly analyzed the determinants of trade flow durations using Cox proportional hazards models. The purpose of this paper is to show why it is inappropriate to analyze the duration of trade with continuous-time models such as the Cox model, and to propose alternative discrete-time models which are more suitable for estimation. Briefly, the

Remission achieved after 2 years treatment with low-dose prednisolone in addition to disease-modifying anti-rheumatic drugs in early rheumatoid arthritis is associated with reduced joint destruction still present after 4 years: an open 2-year continuation study

Objective: To evaluate if remission induced by low-dose prednisolone during the first 2 years of rheumatoid arthritis (RA) in the BARFOT glucocorticoid (GC) study had a sustained effect on radiological damage for a total of 4 years. Methods: A total of 150 of 211 eligible patients with RA who had been randomised to the 7.5 mg prednisolone group ( P) or no prednisolone group (NoP) in addition to th

Models for road surface roughness

This study focuses on the statistical description and analysis of road surface irregularities that are essential for heavy-vehicle fatigue assessment. Three new road profile models are proposed: a homogenous Laplace moving average process, a non-homogenous Laplace process and a hybrid model that combines Gaussian and Laplace modelling. These are compared with the classical homogenous Gaussian proc

Information activities and appropriation in teacher trainees’ digital, group-based learning

Introduction: This paper reports results from an ethnographic study of teacher trainees’ information activities in digital, group-based learning and their relation to the interplay between use and appropriation of digital tools and the learning environment. Method. The participants in the present study are 249 pre-school teacher trainees in Sweden. Three key informants and their teams were followe

Considering fungal:bacterial dominance in soils - Methods, controls, and ecosystem implications

An expectation in soil ecology is that a microbial communities' fungal:bacterial dominance indicates both its response to environmental change and its impact on ecosystem function. We review a selection of the increasing body of literature on this subject and assess the relevance of its expectations by examining the methods used to determine, the impact of environmental factors on, and the expecte

Dual-VT 4kb Sub-VT Memories with <1 pW/bit Leakage in 65 nm CMOS

Two standard-cell based memories (SCMs) for op- eration in the subthreshold (sub-VT) region are presented. The SCMs accomplish the task of robust sub-VT storage and fill the gap of missing sub-VT memory compilers. The storage elements (latches) of these SCMs are custom-designed cells using a dual- VT approach to balance timing. Additionally, two read-logic styles are presented: 1) a segmented 3-st

Large-scale monitoring of waders on their boreal and arctic breeding grounds in northern Europe

Large-scale and population-wide monitoring of waders on their boreal and arctic breeding grounds has hitherto been lacking, mainly because logistics are truly challenging in regions with few ornithologists, vast areas and few roads. In Norway, Sweden and Finland (here 'Fennoscandia') there are now national monitoring schemes in place, aimed at tracking all bird species, which allows trends to be e

Remotely-sensed, nocturnal, dew point correlates with malaria transmission in Southern Province, Zambia: a time-series study

Background: Plasmodium falciparum transmission has decreased significantly in Zambia in the last decade. The malaria transmission is influenced by environmental variables. Incorporation of environmental variables in models of malaria transmission likely improves model fit and predicts probable trends in malaria disease. This work is based on the hypothesis that remotely-sensed environmental factor

Baltic-Finns and Scandinavians : Comparative-Historical Linguistics and the Early History of the Nordic Region

The study investigates how the early nineteenth century invention of comparative-historical linguistics affected European ethnohistoric thought, and how this process altered ethnohistorical research on the early, pre-Christian history of the Nordic region. The case study of the Nordic region (Denmark, Iceland, Norway, Sweden, Finland and Estonia) includes the discipline histories of Finno-Ugric st

Rural avenues as dispersal corridors for the vulnerable saproxylic beetle Elater ferrugineus in a fragmented agricultural landscape

Understanding factors that limit gene flow through the landscape is crucial for conservation of organisms living in fragmented habitats. We analysed patterns of gene flow in Elater ferrugineus, an endangered click beetle living in old-growth, hollow trees in a network of rural avenues surrounded by inhospitable arable land. Using amplified fragment length polymorphism (AFLP) data, we aimed to eval

Effect of Hydrophobicity on the Interaction between Antimicrobial Peptides and Poly(acrylic acid) Microgels

The influence of peptide hydrophobicity on the interaction between antimicrobial peptides and poly(acrylic, acid) microgels wits studied by end-tagging the kininogen-derived antimicrobial peptide GKHKNKGKKNGKHNGWK (GKH17) and its truncated variant KNKGKKNGKH (KNK10) with oligotryptophan groups of different lengths. Microgel deswelling and reswelling in response to peptide binding and release was s

Median and Ulnar Nerve Injuries in Children and Adolescents- Long-term outcome and Cerebral reorganisation

A peripheral nerve injury may lead to serious disability and influence the individual´s quality of life. It is considered that children can regain better sensory and motor function after a peripheral nerve injury, but the exact mechanism behind such superior recovery is not known. The aim of the thesis was to study the long-term clinical outcome after a peripheral nerve injury in patients injured

Cobalamins uncovered by modern electronic structure calculations

This review describes how computational methods have contributed to the held of cobalamin chemistry since the start of the new millennium. Cobalamins are cobalt-dependent cofactors that are used for alkyl transfer and radical initiation by several classes of enzymes. Since the entry of modern electronic-structure calculations, in particular density functional methods, the understanding of the mole
