Objective. In cross-sectional studies, elevated osteopontin (OPN) levels have been proposed to reflect, and/or precede, progressive organ damage and disease severity in systemic lupus erythematosus (SLE). We aimed, in a cohort of patients with recent-onset SLE, to determine whether raised serum OPN levels precede damage and/or are associated with disease activity or certain disease phenotypes. Met

In longitudinal studies, changes in participants’ cognitive performances can partly be attributed to variations in the testing situation (testing specific factors), such as, different test administrators or different testing environments. Focusing on test administrator influence, testing specific factors were examined in a Swedish longitudinal study of ageing. Test scores from 6,686 examinations r

Aim: To describe the Swedish Neonatal Quality Register (SNQ) and to determine its completeness and agreement with other registers. Methods: SNQ collects data for infants admitted to neonatal units during the first four postnatal weeks. Completeness and registers’ agreement were determined cross-linking SNQ data with Swedish population registers (the Inpatient, Medical Birth and Cause of Death Regi

BACKGROUND: Empirical research suggests that household debt and payment difficulties are detrimental to mental health. Despite well-known measurement problems that may contaminate analyses using subjective self-reported health measures, our knowledge is very limited concerning the effect of payment difficulties on 'objective' measures of mental health. Moreover, few studies use longitudinal data t

Background and Objectives: Fetal RHD genotyping of cell-free fetal DNA from RhD-negative pregnant women can be used to guide targeted antenatal and postnatal anti-D prophylaxis for the prevention of RhD immunization. To assure the quality of clinical testing, we conducted an external quality assessment workshop with the participation of 28 laboratories. Materials and Methods: Aliquots of pooled ma

Idiopathic pulmonary fibrosis (IPF) and lung cancer represent progressive lung diseases with a poor prognosis. IPF represents a risk factor for the development of lung cancer, and the incidence of lung cancer is increased in patients with IPF. Disease pathogenesis of IPF and lung cancer involves common genetic alterations, dysregulated pathways, and the emergence of hyperplastic and metaplastic ep

Double quantum dots (DQDs) hold great promise as building blocks for quantum technology as they allow for two electronic states to coherently couple. Defining QDs with materials rather than using electrostatic gating allows for QDs with a hard-wall confinement potential and more robust charge and spin states. An unresolved problem is how to individually address these QDs, which is necessary for co

Particle-assisted III-V semiconductor nanowire growth and applications thereof have been studied extensively. However, the stability of nanowires in contact with the particle and the particle chemical composition as a function of temperature remain largely unknown. In this work, we use in situ transmission electron microscopy to investigate the interface between a Au-Ga particle and the top facet

The essence of ELI-ALPS, the laser driven secondary sources ranging from X-ray and X-UV to THz with duration as short as tens of attoseconds, are designed to be available for users from 2016.

Introduction: Patients with systemic lupus erythematosus (SLE) have persistent platelet activation and an increased risk of thrombotic events, which cannot be accounted for by traditional cardiovascular risk factors. Factor (F)XII has a potentially important role in thrombus formation and is triggered by activated platelets. We therefore asked whether the contact system is involved in inflammation

Dysregulation of lymphocyte function, accumulation of autoantibodies and defective clearance of circulating immune complexes and apoptotic cells are hallmarks of systemic lupus erythematosus (SLE). Moreover, it is now evident that an intricate interplay between the adaptive and innate immune systems contributes to the pathogenesis of SLE, ultimately resulting in chronic inflammation and organ dama

Introduction: An antenatal corticosteroid (ACS) delivery interval of 24 h to seven days is commonly referred to as optimal timing. We aimed to investigate whether the ACS delivery interval was associated with the obstetric indication for treatment and with neonatal complications. Material and methods: The study was a retrospective chart review of clinical data from preterm neonates delivered at th

This paper considers the long-term effects of smoking on disability retirement in Sweden. Smoking is known to have damaging effects on health, but there is limited evidence on how the effects of smoking translate into worse labour market outcomes, such as the inability to work. In contrast to the few previous studies on smoking and disability retirement, we use a large population sample with regis

The leucine-rich repeat kinase 2 (LRRK2) p.G2019S mutation is the most common genetic cause of Parkinson's disease (PD). An induced pluripotent stem cell (iPSC) line CSC-41 was generated from a 75-year old patient diagnosed with PD caused by a p.G2019S mutation in LRRK2. Skin fibroblasts were reprogrammed using a non-integrating Sendai virus-based technology to deliver OCT3/4, SOX2, c-MYC and KLF4

Mutations in the PARK2 gene, which encodes PARKIN, are the most frequent cause of autosomal recessive Parkinson's disease (PD). We report the generation of an induced pluripotent stem cell (iPSC) line from a 78-year-old patient carrying a compound heterozygous mutation (c.823C > T and EX6del) in the PARK2 gene. Skin fibroblasts were reprogrammed using the non-integrating Sendai virus technology to

Over the past decade, III-V heterostructure nanowires have attracted a surge of attention for their application in novel semiconductor devices such as tunneling field-effect transistors (TFETs). The functionality of such devices critically depends on the specific atomic arrangement at the semiconductor heterointerfaces. However, most of the currently available characterization techniques lack suff

The physical properties of material largely depend on their crystal structure. Nanowire growth is an important method for attaining metastable crystal structures in III-V semiconductors, giving access to advantageous electronic and surface properties. Antimonides are an exception, as growing metastable wurtzite structure has proven to be challenging. As a result, the properties of these materials

Defective production of antiviral interferon (IFN)-β is thought to contribute to rhinovirus-induced asthma exacerbations. These exacerbations are associated with elevated lung levels of lactate dehydrogenase (LDH), indicating occurrence of cell necrosis. We thus hypothesized that reduced lung IFN-β could contribute to necrotic cell death in a model of asthma exacerbations. Wild-type and IFN-β-/- m

The Sendai Framework for Disaster Risk Reduction highlights the importance of all-hazard and multi-stakeholder approaches. This requires exchange and integration of risk information across sectorial and administrative borders. This paper focuses on challenges and prerequisites for aggregating risk information from multiple stakeholders in disaster risk management systems. Aggregation is here under
